Does anyone have any suggestions/rumors/theories about it?
I hope its like F-Zero GX for GCN because that one was amazing, and strangely developed by Sega. (Heh, Sonic gave them a few tips?) The only things I didn't like were the uninspired characters, the lack of the Mute City song or any good F-Zero music. (Some of the music was...okay, but the C. Falcon theme song, for example, goes into the Sega cheesiness category.).
Hopefully, if they bring back Story Mode, it won't be so hard. (Not to mention that to get all of the prizes in the game you need to beat the already impossible missions on Hard and even Very Hard.
