Sega teases Sonic and Puyo Puyo anniversary projects
According to Andriasang, Sega teased multiple "projects" for both series' anniversaries, though the nature of those projects is unannounced. The last Puyo Puyo game was 2009's Puyo Puyo 7 for PSP, Wii, and DS, so that series is ripe for another sequel. As for Sonic, it seems safe to assume we'll see a few Sonic games in 2011 — not because it's a big anniversary, but because it's a year.
