I suppose, but I wouldn't take it as a point of pride that they're being outstripped by a last gen console. Not to mention that I still believe the Wii will peter out. It's an interesting concept but once the PS3 starts rolling out serious software (and hopefully drops their prices, or they're doomed) people will give up on the Wii. Mind you, I may just be clutching at straws out of brand loyalty. Until such time as they call it done, though, I wouldn't count them out.
As for the DS, however, that's another matter. The handheld market has always been and will probably always be Nintendo's territory. The PSP is to handhelds what the XBox is to stationary consoles. An excellent system for people who like to play games that suck.
