Yet another plate of theories and ideas for the Transformers sequel...

Upon reflecting on several viewings of the Transformers movie, I had a few thoughts and ideas. I guess I'm just looking to the Transformers fan community at large for opinions...
First of all, did anyone notice the sliver of the allspark that remained after Sam did MovieMegs in? If one were to ask me, I'd suspect that little piece could eventually become a little trinket called the Key to Vector Sigma.
Secondly, since the remnants of the decepticons were sent into the depths of the ocean, the debut of the decepticon underwater bunker starts to seem likely.
Thirs, since everyone's well aware we have the essence of two of the Combaticons floating around, is it such a far stretch that the first Gestalt we see be Bruticus, and not Devestator?
And as far as the speculation for the next cast of robots goes, something tells me that we'll get Autobots Wheeljack, Trailbreaker, and one other minibot, and given the current taste of Decepticons, I'd suspect Thrust, a Gestalt, and maybe Scrapper.
I'd love to hear your theories. It'd brighten my day.
