Oddly enough, I didn't have to convince her at all.  She wanted to play a Wii game because she saw I was frustrated that it never gets used.  She looked at the few games we have and didn't want to play any of them.  So she went online to see what Wii games we out or upcoming that we could get.  While on Amazon, she decided to see what PS3 game are out or upcoming.  Then she looked over at me and said "um, Little Big Planet, God Of War III, Heavy Rain, exclusive Joker on Batman...sell the Wii!".  And the rest is history...lol. 

I am undecided, and I have to convince my wife also.  Here's the quick story.  We bought a Wii in December 2007.  It hasn't been played once since I got my Xbox 360 in September of 2008.  We have Wii Fit.  We played it once.  Now we like the Wii, for games like Mario Galaxy, Mario Kart, Trauma Center, and No More Heroes, but that's about it.  My wife wants to keep the Wii to play Mario Galaxy, but she hasn't played it since we got it, and she is a full time student in pharmacy school, so she only plays games over the summer, in which this summer she played Fable 2 only, so nothing on the Wii.  I want a PS3 for Uncharted, Killzone, Metal Gear 4, Heavy Rain, Little Big Planet, Resistance, etc. and Bluray.  She only wants it for Heavy Rain.  I would miss the Mario games also, but obviously not much since I haven't looked at them in over a year.   With the price drop, I could probably sell my Wii with extra controllers and Wii Fit and get enough money for the PS3 Slim.  Any ideas as to how to convince my wife to ditch the dusty Wii for a PS3?
