Depends on what you mean. I think it helped the sales. But if you're referring to the game itself (which I think you are), then...
Yes, I believe it hurt the game.
Not the fact that it was pushed back. In fact, I think it needed to be pushed back more. The game was rushed; it needed more time. I also have a personal issue with the Wii version in that it mirrored the game. It seems silly and pointless to me, and I don't like it that it's a change from how the game was intended. It's one of the prime reasons I got the GC version.
The time they had to take preparing the game for both systems to me is time they could have spent on improving the game. But there's another aspect. With how long they took to release it, it would have probably hurt sales to release it on only one. With the timing of the release, they kind of had to do both consoles. But I think that in order to perfect the game more, they probably should have waited longer and made it a Wii exclusive.
So, I think it helped the sales, but hurt the game itself.
