This is the Xbox 360/PS3 version

Edit:  It appears the youtube videos have been pulled.  This vid replaces them both anyway.

It is in HD here (It is very slow): http://ruliweb.empas.com/data/rulinews/read.htm?num=16554

It is in Korean I think.  The last two links under the HD section might be the youtube videos that were above which had the cutscene in the first vid and the hubworld with some an action stage in the second vid.

If this vid is taken down too, let me know because I have more links.

gameplay reminds me of sonic rivals, can't wait to try out the game.

Ignore this post.

i have yet to play a sonic game in 3D worth the price of admission, you're all fools if you trust sonic team

I liked Sonic and the Secret Rings. I'm a fool.

I think that it looks good.

This game kinda looks fun.

That cut scene was amazing. wonder if that's what Sonic will look/play like like next Gen.

Still the game play looked great, reminds me of the first time i played Sonic Advanture.

SONIC IS BACK!!
