One would assume that Sonic Team would treat their one true crown jewel (unless you count the various Phantasy Star games before Online) with a silk glove, but the general attitude that seems to be coming from them (notably again working on multiple projects at once) makes me feel more like the final product will be treated more with gauntlets. Sonic V. Mario? What the crap is that? Doesn't Sega realise that Mario and Sonic will not mask that Olympic games always suck?
On a somewhat related note, the Sonic RPG intrigues me, especially because it is being done by a different developer, thus keeping it from Sonic Team and keeping Sonic Team away from anything that isn't NiGHTS.
