To be honest, i don't like ubi so i really don't care about this particular game.
But the wii will probablly turn out like the DS, first party with maybe 1 third party game thats good or high profile in the first year. Thats basically what castlevania for the ds was. I know we've all seen the pie, pac-man eating everything is mainly nintendo, and now third parties are trying to do something to get a piece of the pie, although they aren't doing a good job, except for square.
Expect crappy ports for the first year, or just crap. If nintendo can make the wii set off on fire like the DS, then maybe we'll see games designed from the ground up for the system that are high calibur. Either way, personally I'm only intrested in nintendo games right now, and maybe elebits. The DS and catch up old games will hold me over till wii picks up the first party steam.
