On two sites, two mysterious timers have appeared, signaling the announcements of somthing possibly massive. The people at Kotaku compair both timers to be similar to Legend of Zelda, and Super Mario Brothers, even though the two developers are Sega Japan, and Marvelous Entertainment (Never heard of them before this, or if I have I can't remember).
In any case, one timer is set to hit 0 friday night, the other.... I fiddled around and I'm guessing Midnight of Thursday (As in the instant it turns into friday, timezone unsure). We'll be finding out about this soon. Until then, feel free to speculate.
