God doesn't want you to make a big mistake. That's why it isn't selling.
Like already stated, this is the WORST possible time for a JRPG fan to sell his Wii. Last Story, Xenoblade, Dragon Quest X...
However, if you really need the money, like right now, then go ahead. The PSP had a great year coming, yet I was forced to sell it, because I had very little money... 
However, I highly recommend that you keep your Wii for at least a couple of months. 2010 is gonna be a great year for the Wii.
