PREDICTION: SONIC.
No original reasons though, like everyone says, great Sega-Nintendo relationship, X'mas release of the Olympics game. The European guy REFUTING Sonic is actually a good sign; spokespeople are usually non-committal about things, but this could indicate that there are strict orders from headquarters to be extra tight-lipped about this and flat-out lie when asked upon by reporters.
Something marginally original: Sonic & Mario Olympics might be a byproduct of Sonic in Brawl negotiations. Nintendo I'd imagine would want the votes to count for something so as to maintain future fan interests, so negotiations started soon afterward. Maybe this Olympics game is actually a term in the contract; I mean, Nintendo has never given up control of the Mario characters anywhere else, neither has Sega on Sonic. A little quid pro quo if you ask me.
I'd put the odds at over 75%.
ps. yes, i read that miyamoto would be supervising the project also. but A) sega is gonna be publishing this and B) miyamoto pretty much supervises everything...
the Wii is an epidemic.
