As others have already said - yes this lineup is weak, but:
1. I am certain the lineup for the rest of the year will look very diffeent
2. There are very probably more than a few good to great Wii games that you haven't played yet, many of them available at bargain prices.
For me personally I couldn't care less, even ignoring the 3DS that I bought, I have a serious backlog of Wii games I already bought
