Well, as it turns out, the folks behind BotCon decided to release pictures of Thrust yesterday, so I wasn't too far off in my predictions.
But anyway, this marks the first time since 1985 that Hasbro has released all six characters using the same basic "Starscream" mold (or a variation thereof). Most of these characters have seen other forms over the years, some more than others, but never before have updated versions of the original forms of all six characters been available at the same time. Although some fans are angry at Fun Publications--believing that, had FP left well enough alone, the characters which are now BotCon exclusives would have been eventually released by Hasbro at mass retail--the fact that no mold has ever been used to recreate all six characters since 1985 argues rather strongly against this. FP should be commended, rather than criticized, for their efforts.
So, in honor of this nostalgic achievement, here is a quickly hashed-together image of all six characters, together again for the first time in over two decades!
