Time will tell what we see, however I really don't understand why Hasbro does this. We finally get to a Fanfirst Friday, they have something that isn't leaked and they let someone else reveal it. Now, as per norm, people will complain that we didn't see anything new.
I mean, they may surprise us with something new still but for a "Fanfirst" they generally do everything in their power to let things get revealed elsewhere.
I am hoping that it's a mistransformation.
Other than that, the front profile and alt mode looks excellent. Looks like he has a nice ab-crunch too.
