The last shot is unbelievable good! The donut looks great!

Sonic can put poop on a stick and sell it for 50 bucks and id still bite... This actually looks better than poop on a stick. So yay!

Wish they were a little sharper still, but it looks at least as good as Black Knight, which we should expect.

Graphically,it is a...WTF?!?!?

They've obtained to improve the Black Knight engine,woah! XD

One of the sources says that high resolution scans are expected as early as tomorrow.

i can't see much, but it the 3D levels look similar to unleashed (they were telling the truth :p), and the 2D levels look like Sonic 4 ep1

gonna get some major info on this at E3 hopefully

Well we're going to get more info when my Nintendo Power comes in.

looks pretty good

Visuals are great, but that's par for the course with Sonic Team on Wii.  Hopefully Ogawa's in charge again, Secret Rings is the closest Sonic's gotten to "good" since he went 3D.
