Please be in Seattle, Boise, or Portland! I frankly think that it could be a Fallen, Nemesis Prime, or a futher advancement in Shattered Glass (I dunno, maybe it could be the originel Movie in shattered glass)
Primus is a huge battle planet bent on consuming the universe
they could have Optimus reincarnated by Primus as...Nemesis Prime
The Decepticon's make a tentitive alliance with the germaphobic Junkions after crashing on their homeworld
Galvatron is given the Decepticon matrix from teh creator of Transformers, Unicron. Galvatron is now empowered with new energy (could be a new deco or a new figure)
Primus invades cybertron and is interrupted in progress by the junkions and Decepticons
Galvatron attacks Nemesis within Primus' own body
Hot Rod had followed Nemesis to find his new power, and during the fray between the two leaders, snatches the Autobot Matrix from Nemesis and begins to absorb its power
Galvatron manages to gain the upper hand, but before he can capture him Hot Rod newly empowered (in the RTS Prime mold) as Rodimus Prime grabs Nemesis and throws him out into deep space
Optimus begs Rodimus to use the power of the Matrix to kill Primus. Rodimus agrees only because Primus is a threat to both factions, and uses the matrix to defeat Primus in a glorious display of power
Galvatron retreats to earth while the new leader of the Autobots towers over cybertron. Galvatron however is dreading future battles, as a new menace is ruling the Autobots...
shhhh! No spoilers
