February was a big month for Microsoft's hardcore side: Bulletstorm, MvC3, NBA, Dead Space 2, and BLOPS's sustained selling point. Kinect continues to grab the casual audience which remained interested post-holiday season. Now if it will sustain in the long run, we'll see. Its hardware boost is expected, considering both factors.
Nintendo did fairly well, despite the odds. Hardware actually went up this time as opposed to down, which people estimate will happen. Just Dance 2 is the casual game of 2010 for Wii, and Nintendo is lucky it became a hit, and I guarantee you Michael Jackson's game was mostly Wii sales, too. No mention of Mario Sports Mix is not endearing, though; it probably sold ~250k at best. The ad was poor and the timing was bad. Thankfully for Nintendo, the game sold very well in the long run in Japan, so perhaps long legs will follow.
Sony even went up in hardware sales, also thanks to the hardcore game push this month. Killzone 3 also was a factor, that was for sure, but maybe not the biggest reason. Move is still selling, but its impact is smaller than Kinect, by far. Thankfully Sony has major releases each month moving forward, ensuring at least one big game in the Top 10 a month.
Now, next month. Nintendo not only released Pokemon B+W which will most likely get close to or be at top of next month's chart, but the 3DS will be launching in March as well. I personally think that Nintendo is releasing the 3DS now in the US rather than earlier in order to pull casual attention away from other innovative products such as Kinect and Move. Whether it will or not depends on word of mouth. Price will also be a factor.
The following games will appear next month, IMO:
BLOPS
Just Dance 2
Zumba Fitness
Michael Jackson
Dragon Age 2
MLB 2K11
Homefront
Crysis 2
Pokemon Black and White
Insert 1 or 2 3DS launch titles (if some of the above do not appear)
