Sonic Rush Adventure hands-on at IGN.

"Dimps created the original Sonic Rush close to two years ago. The game was a very, very good old-school style Sonic the Hedgehog game that introduced two-screen tall level designs and some nifty trick-based combo systems. After experiencing one Sonic the Hedgehog game after the other on the Game Boy Advance, it's kind of surprising to see that Sega gave the furball a bit of time off on the Nintendo DS. Not anymore, as the company is working with Dimps again to offer up a follow-up to the 2005 platformer hit set for release in just a couple of months."
