Gamin' NEWS! Sonic 20th Anniversary «Generations» Teaser Trailer

So here it is.

The first video of Sonic's 20th Anniversary game!
Well, just a teaser trailer, through it probably hints at what we might come across, be it content-wise or direction.

So let's check it, ok?



Alright.
Coming in 2011 on Xbox 360 and PS3.

So what do we get from this?
It looks like the rumours about an anniversary title featuring old levels remade might be true.
Also I guess Sega was really buying the trademark "Sonic Generations" as reported by fans, a fitting name for such direction.
Classic and modern Sonic side by side?
Could this be an "event", a crossover game? Remixes of old stages? Revisiting past zones?
A Crisis of Two Hedgehogs?? (ha!)

I'm guessing something close to Sonic Unleashed/Colours gameplay wise, from what the first part of the video hint at.
And I wish a funny plot, that shouldn't be hard to write. I mean, make Eggman cross over time to conquer the world, the classic Sonic teaming up with the current one? And humour. LOTS of it!

Anyway, hyped!
