They could have done a flashback with this Sentinel Prime just to get that into the comic. Or tell it in two parallel stages, with him being the core hero of a past-set story, and the current bots trying to get a Macguffin he protected or his or whatever. It was kind of a schmozz anyway.
I love the Springer they ended up with, and one of the fun ideas I've idly played with for some time has been to find a story for Springer getting split into two bodies (this one and the Generations/GDO/whatever helicopter). Or hell, maybe these are like Springer Soldiers or something, sidekicks or fans of his that emulate his look and style or something.
But as much as I like the Springer, it would've been cool to get the mold in these colors. It's just such a cool mold. I'm glad to get the first Cybertron Hot Shot design again, but we really gotta see this one revisited too.
