Sonic coming back in 2D this summer

In an interview with GameSpot, Sega associate brand manager Ken Balough revealed a few more details about Sonic 4. Specifically, he said the game will pick up the series after Sonic & Knuckles and incorporate established 2D gameplay mechanics for the series like the spin dash and power sneakers. Additionally, the game will incorporate leaderboards for players to test their speed against one another and will incorporate motion controls on the Wii and PlayStation 3 (with the Sixaxis controller, not necessarily the upcoming "Arc" motion controller.)
