Time to bump this up, with some new info:
Gamecube - Madden '08
Xbox - also Madden '08 (UPDATE 9/5/08: And that'd be Madden '09 now.)
GBA - Anything else coming out? If not, what was the final release?
What were the last releases for the N-Gage and Gizmondo?
For anyone wondering why Nintendo has Zoop listed as the last SNES release instead of Frogger: as you may know, at the end of the SNES lifespan, Majesco got the rights to reprint several SNES and Genesis games, and Zoop was probably one of the last SNES reprints to hit stores (if not the last).
