Hopefully with Wheeljack coming out this means ....dun dun duuuu.... Sunstreaker will finally see the light of day!!
You know....since their transformations and even heads are quite similar.
Coneheads seem to be a likely candidate for next Mp's. Takara, being the business it is, I believe thinks about the lowest costing and highest profiting toys.
However Jazz should be the next new toy(after wheel.J and BB) but we will definitely see a few more MP seeker's, Blaster, then Coneheads. Hopefully Mirage will follow soon.
