Sonic 4 coming to the iPhone/iPad?

Sega surprised everyone last night with the reveal of Sonic the Hedgehog 4 -- apparently the newest game in the series will be a download-only episodic title coming to the Xbox and PS3 later this year. And the iPhone, too? The very end of the trailer, as you can see above, has a blank rectangle after the XBLA, PSN, and WiiWare logos, which some presume is a space for the App Store logo eventually. In addition, various graphics were found on the official site that hint at an iPhone release as well. The game, which you can see in the trailer linked above, is a colorful return to the series' 2D roots, but even the updated 3D graphics are probably enough for the latest versions of the iPhone to handle.

And of course there's the iPad -- considering that the game is called "Episode 1" (so presumably Sega is going to be releasing a few of these), Sega will probably want as big an install base as possible. Just widening the display of an iPhone app might not work so well, as these simulator screenshots on Gadget Lab show, so it's very possible that one of the launch games for Apple's tablet could be a sweet, high-resolution old school Sonic sequel. We'll keep you updated -- just watch out for the drool.
