Sonic HQ

Reading through the latest Nintendo Power I stubled across an article about Sega developing for GBA (GameBoy Advance) and GCN (GameCube). Finding this rather surprising, I read through the whole article which was mostly about the GBA games Sega is developing. The titles anounced were ChuChu Rocket GBA ( or ChuChu Rocket Advance), Puyo Puyo, and Sonic Advance. No GCN titles were anounced.
