Sega delays Sonic 4 till later this year (but there will now be an iPhone version!)

It would appear that Sonic 4 has been delayed until the “latter half of 2010.” That’s the bad news. The good news? One, there’s a new trailer. Two, it’ll also come out for the iPhone and iPod touch (in addition to the platforms we already knew about). Hear that, Nintendo?

The full title of the game is Sonic the Hedgehog 4: Episode I, which is something of a mouthful. I’ll just say Sonic 4 from here on out.

In any event, the game has been delayed in order to “allow for more careful focus on the design of each level and to provide additional polish that an important game like this demands, ultimately providing fans with an unrivaled classic Sonic feel.”

Sonic 4 is a perfect fit for the iPhone. I mean, the controls consist entirely of holding the D-Pad left then occasionally pressing the jump button.

It’s probably too late to call anything on the iPhone a “killer app,” but Sonic 4 certainly fits the mold.
