Sure,
Sonic the Hedgehog 4 may have been
delayed to the end of the year... but there is some good news to the delay. Well, for iPhone users that is...
In conjunction with the delay and official announcement of the iPhone version, Sega has since stated that the iPhone port of the game will have 2 exclusive stages included in its version. These stages will be unique to the system and take advantage of the platforms tilt control capabilities. While details beyond that are sketchy, some rumors state that these levels will be the previously shown mine kart levels which were scrapped from the console version(s).
Come on, you know you will want to buy the game multiple times... you have to...
