I suspect that the USS protostar will likely be the next ship that Playmates rolls out as they have a full wave of Prodigy characters set to debut this fall as well. Paramount is hot to get the kiddos interested in Star Trek, so I think there will be a big focus on the Prodigy toyline since its the entry level media for the brand.
For me personally, Id love to see the SNW Enterprise and figures from that show. And as much as I adore the old Art Asylum Enterprise figures, I hope that Archer and Co get produced in the new Universe line.
Honestly, the best part about the launch of the new toyline is being interested and excited for new stuff to come.
