Kirk/Rand
Spock/McCoy
Sulu/Chekov
Uhura/Scotty
Medical McCoy/Chapel
Taken Rand & Chapel out of wave 5 and replace them w/ the Enterprise Incident Kirk and Romulan Commander, who still don't have a home.
It would have gotten Chekov out, who is conspicuously absent, still given us Rand and Chapel, and left a potentially open slot in wave 5 if they wanted to also replace the stand-alone Medical McCoy with something else. It would've also forced a bump in sales for the Kirk/Rand 2-pack and the Medical McCoy / Chapel (combating Kirk fatigue and the rather obscure McCoy variant) for those who really want R & C.
Those were the 2-packs I was expecting albeit with two versions of Kirk rather than McCoy (maybe evil Kirk in the Rand pack). I'm more of a movie fan myself but these are very tempting, especially with Chapel and Rand as part of Wave 5. I'm also keeping my fingers crossed for similar TMP 2-packs with Decker and Ilia added to the mix
