Alot of this Wii isn't hardcore sillyness is due to lack of steady new monthly hardcore game supply, I assume. But by the end of it's first year the wii will have been graced with a mario title, a paper mario title, a zelda, and a metroid. I know 2 were ports, they shouldn't count, but they are on the platform. We didn't see this kind of support in the DS's first year at all, and becuase of that DS and PSP were deadlocked in equal selling rates, that were decent. But the DS exploded in its second year, redesign yes, but new super mario bros and the fall/winter line up for that year were big and the previous year's titles (the few that were truly good) were also available. You can see the same trend with the 360, obviously not hardware numbers, but with software. The 2nd year coming into the fall and christmass season the 360 has a great line up.
My guess is 3rd parties are going to be late to the party because they dismiss the Wii now as if it won't have a more polished line up next year. The damn thing sells itself WITHOUT new software every month, the september NPD numbers prove that. And the same effect with the DS will most likely occur on the Wii. With that said, remember even with the PSP's horrible software sales it still get 3rd party support which is quite good, and the 360 is no PSP. So expect 3rd parties to be more stubborn and not support the Wii, or at least not support it to the fullest.
