Sonic 4 delayed until late 2010, will be released on iPhone

Sega just dropped two items of information about Sonic the Hedgehog 4: Episode I, one slightly disappointing and one ... interesting? First for the kind of bad news: it's been delayed from its original "summer" release to "late 2010."

"The additional time will allow the Development Team to focus on ensuring overall high-quality throughout the game by continuing to tune, balance, and maintain the kind of polish that an important title like this demands," the press release reads, "and ultimately providing fans with an unrivalled classic Sonic feel."

The other news: as many suspected, the downloadable game will be released not only on PSN, XBLA and WiiWare, but for the iPhone / iPod Touch as well. You'll have the choice of portability or buttons!
