I'd say wait till the end of this year (it's a safe bet the demand isn't going down any time soon and if you sell it during christmas you get the most for it) but really if you're not happy with whats on the Wii after this year then there's no hope for you I believe :P
You have things like:
MadWorld
The Conduit
House of the Dead
Sonic and the Black Knight
TMNT Smash Up
New Zelda this year hopefully
New Nintendo stuff
Let's tap
and a huge list of other titles coming so just looking around will help
So yeah play a few of the great 2009 games if you don't like them then w/e the Wii isn't for you I guess lol.
