As for the Wii, well... Nintendo never really had as many third party titles as Sony and Microsoft had, so I think it will come in last in the console wars just based on less games available.
Rumble is pointless. I don't care if they put it back or not because I really don't miss it at all (especially in games that really make full use of the sixaxis like Motorstorm). The rest of what you listed should definitely be fixed. I was slightly bummed to find out that I couldn't listen to my music while I was playing my video games because you can do that with the 360. I'd also like DivX/XviD playback, but that will never happen considering those two codecs are copyrighted and are not for public use.
