Commander class Rodimus Prime. Apparently he'll come with blast effects, fishing rod, will be voyager sized, but leader parts count, and his trailer will be very similar to MP09's, in addition to the fact that his chest will be able to house the Matrix.
Voyager Dinobot has perfect proportions, but will be in toy colors, not Mainframe colors.
And I'll just quote their statements about Galvatron because I don't really know how to effectively paraphrase because I have no idea what most of the statement means:
Galvatron is... weird?
His railgun (at least in early versions) looks like Lockdown's face gun and is compressed into the orange cannon (similar to MPM Megatron's fusion cannon).
The hands should be able to open for the matrix he comes with.
Galvatron himself easily beats the **** out of TR (I mean, the standard is too low to not suck), but I don't see it worth leader class. Not sure how the final version would turn out.
So it sounds like next year is the year of Matrices Though, Rodimus sounds interesting... I'll need to see in hand images, but it sounds kind of promising
