It's not that SEGA doesn't want to make a more serious game of the olympics for the Wii, they just doesn't need to make anoter game of the exact same topic when the one they already produce is a total succes.
SEGA is making a olympics game for the 360/ps3 just because they need to take advantage of such important licence.
Dont take it personal, it's just businness.
My definition of fanboy: An idiot that misses 2/3 of the fun.
