Looking at the games slated to release for both the Wii and PS3, I view a greater potential boost for the PS3. (in terms of percentage to what is selling right now)
That is because if you look at the Wii games, won't most people who want to play NSMB, Wii Fit and Wii Sports Resort already own a Wii? Then that leaves Tales of Graces, which could see a small boost, but that is mitigated somewhat because of people who bought a Wii for ToS:DotNw. Then we're left with MH3, which to me should cause the biggest boost of any of the aforementioned. But looking at the predictions TheSource made of 1st week sales for MH3, it's not looking like the popularity of MH on PSP will translate equally to the Wii. However, it should still provide a very nice boost. I actually think if MH3 wasn't be released, I would give the nod to Sony for the year. But that is irrelevant since it is coming.
Now with the PS3, you have FFXIII and maybe GT5, which are both mitigated by by a Demo and Prologue, but I think those mitigation's are comparatively smaller then the Wii ones. I think there is a greater opportunity for growth potential with the PS3 games, especially with FF. Then there are the smaller/moderate releases like Tekken 6, ToV, EoE, Trinity Universe etc. that should provide decent boosts as well.
I'm not saying the PS3 will outsell the Wii, but I do think the potential is there. (albeit still very unlikely) Although the rate of sold to previously sold will obviously be superior on the PS3, but that would be a shallow "victory" for Sony.
