IGN has posted the Transformers-trailer shown at last years Tokyo Game Show. Although I've seen the screenshots, it is fun enough to see them actually moving. Wait, I mean 'fun' as in 'obvious understatement'. But you already guessed that, non?
Also noteworthy is the fact that it uses a remixed version of the Transformers: The Movie theme. On a less positive note, I can't see this happening in real time. It looks very pre-rendered to me. Let's hope Winky Soft can deliver the goods, or else Infogrames will remain our last hope.
I think we can now also safely say that it'll definitely be a PlayStation 2 game. No word about other versions though. (Considering it's main fan-base has grown up an Xbox version wouldn't be that odd. Likewise a GC version would fit in nicely with the 'kiddie toys' they are. But I guess Takara just wants the biggest possible userbase.)
