Star Trek: The Animated Series/Adventures will be the next Trek TV series to be distributed in glorious HD on Blu–Ray Disc. When the show was remastered for DVD back in 2006, it was scanned with HD masters in mind, so this release will use the same masters as that release, although you'll see more detail by virtue of the scan not being knocked down to a standard definition format. It's currently unknown if the bonus features will remain the same.
Additionally, several previous releases will supposedly be repackaged with 50th Anniversary packaging and possibly some new bonus goodies to accompany the new releases. This could mean that those of us in the USA will finally have a TNG–R complete series set, but I'm not holding my breath just yet. For the most part, any "new" releases will use the exact same transfers/masters used in the past, so this is really just going to be repackaging of existing material for those who might not have it yet.
On a slightly depressing note, as of right now, the aforementioned additional releases do not include a DS9/VOY remastered Blu–Ray release, at least not just yet anyway. However, that doesn't mean that there won't be some "new" material...
Both of the previously released JJ–verse films will be reissued on 4K Ultra HD Blu–Ray later this year, and Star Trek Beyond will almost definitely be joining them once it's out of theaters. Apparently, the 4K Ultra HD Blu–Rays will utilize new 4K transfers of the original films to take advantage of the Ultra HD format. For those of you wondering how these differ from regular Blu–Ray, 4K Ultra HD Blu–Ray requires a player that supports the format, and displays images four times the resolution of a standard Blu–Ray, and 27 times the resolution of a DVD. (There are other reasons these releases will look better, such as improved color fidelity, but the short version is that 4K Ultra HD Blu–Ray is to 2016 what DVD was to 1996, and not what Blu–Ray was to 2006.) You'll need an Ultra HD TV to take advantage of the format, but if you already have one, and if you enjoy the JJ–verse, these should be exhibits "A" and "B" of UHD technical quality if Paramount handles the transfer correctly. Personally, I'm not sure why these films weren't transferred in 4K to begin with, but the new transfers are a good reason to consider picking these films up again, especially if you plan on investing in UHD anyway. It's also worth noting that this is not the same as regular Blu–Rays that are labeled "mastered in 4K;" those are still 1080p releases that are just taken from a 4K source whereas these discs are actually 2160p UHD, and are making use of that full 4K resolution from the new transfer.
If the JJ–verse isn't your thing, there is one Prime Universe film that's also getting a 4K film transfer and remastering, although whether or not this transfer makes sense will depend on whether or not Paramount releases a 4K Ultra HD Blu–Ray version of the film, which may or may not actually happen. The film in question is The Wrath of Khan, which is the only Trek film to have previously been remastered for its original Blu–Ray release. Apparently Paramount has to decided to rescan the film again, this time in 4K rather than 2K, (once again raising the question of why they didn't just scan the film in 4K to begin with given that it was obvious that UHD was going to be the way of the future when they opted to remaster the film in 2K for the previous Blu–Ray release,) but they've not decided whether or not there will be a 4K Ultra HD Blu–Ray release from the new master, or just another standard Blu–Ray release that has one of those "mastered in 4K" logos on it that just means the film was mastered in 4K, but the disc is still stuck at 1080p. Personally, if this yields a 4K Ultra HD Blu–Ray, I'm fine with it as it gives me more of an excuse to really push for a UHD TV and UHD Blu–Ray player, but if it's just going to be for another standard Blu–Ray release, I think Paramount is making a mistake. We still don't have any other Trek films in the Prime Universe remastered properly, TMP should have its director's edition available on Blu–Ray along with its theatrical cut, and I'd rather see that before seeing another 1080p–only version of TWOK. To be fair to the new release of TWOK though, it sounds like we'll be getting both the theatrical and extended director's editions, so that might be a good way to justify the remastering, even if it would make more sense for Paramount to start with TMP and then do TWOK. If we get a 4K Ultra HD Blu–Ray of TWOK though, that'll be something I pre–order as quickly as a new DST ship.

I'd say the author of that is right on the money with the "thrilled by the good, incensed by the bad" statement. I'm simultaneously thrilled that I'll have both cuts of TWOK available, particularly if they're in 4K Ultra HD Blu–Ray, but also rather irritated that TMP still hasn't had its director's cut restored, that neither DS9 or VOY remastered have gotten underway yet, (nor will they get underway for the 50th anniversary celebration,) and that the other Trek films that need to be rescanned and cleaned up a bit are also still being ignored for commiting the crime of not being TWOK. I'm also not exactly thrilled that Paramount is continuing to push the "TWOK is the center of the universe" angle, because as much as I love the film, there are nine other Prime Universe films that haven't gotten even a 2K remastering yet, and that would benefit more than TWOK from the remastering process unless Paramount commits to 4K UHD Blu–Ray for the new transfer of TWOK to take advantage of the new film scan. If I get that though, I'll be happy with the new scan, and if TNG–R finally gets a complete series release, that'll easily be worthy of the "Fry/Shut up and take my money" meme, as I'll gladly fork over the stones to have all of TNG–R at once, especially since I'll likely have TOS–R by that point, and TAS–R probably won't be too expensive compared to other releases.
