I said "No, by a lot."
The FFXIII boost is all but gone in a week or two, which certainly pushed many consoles up to that point. On the other hand, NSMB Wii will keep on chugging, selling systems in the process. Hell, it'll probably sell close to what GT5 will in 2010 alone.
As it's starting the year with its first price cut and NSMB Wii, it should remain relatively close to PS3 sales until around Q3. Wii Vitality and whatever else Nintendo has for the holidays will have the Wii win Q4 by a pretty large margin, as the console leader normally does (without an FF in the way, that is).
