Sega will be milking the announcement of Sonic the Hedgehog 4 for all its worth, doling out additional announcements and countdown clocks to drum up hedgehog hype. Perhaps the most interesting tease is what appears to be a fourth platform.
Sonic 4 (nee "Project Needlemouse") has been announced as a PlayStation Network, WiiWare and Xbox Live Arcade download, but a handful of observant readers have pointed out that an additional platform appears imminent. Sega's not revealing what that platform is for the time being, leading us to conclude only one thing.
Or iPhone, Games for Windows, Nintendo DS, PSP... could be anything really. Who wants to make some educated guesses?
Update: It appears to be the iPhone. Looks like the Dreamcast 2 launch will have to wait until 11/11/11. :(
