I was really surprised to see this bit of news.
Especially with Sonic 4 coming out on the Wii this year too.
The fact that it's on the Wii and the DS is probably the most interesting bit of news for me so far. Is it going to be like a Sonic Unleashed style platformer on the Wii, and a Sonic Rush style on the DS?
Or maybe it'll be set up like Super Mario Galaxy 2 with a bunch of smaller levels, with some 2D, and some 3D.
