Been not too excited about this movie specially when I firs saw how Megatron looks like.  But when I saw Shockwave's toy, it kinda gave me a little glimmer of hope.

Robot Mode

Tank Mode

But on the second thought the robot mode kinda reminds me of Megatron Leader Class from the first movie.  The built and some elements are quite identical.  But all together I like how it looks especially the badass canon.

And for those who haven't seen Megatron's form, here is the shot.

Robot Mode

Tanker Mode

The toy really looks off but maybe it will look good in the actual movie.  Now I can't really wait to see that Trailer that will come out in Super Bowl.
