Very good Feb hardware sales for MS and Sony. I really wonder how many PS3 sales were left on the table, due to short supply, considering all the evidence of many people being unable to find one at retail price. A quick check on Amazon also supports this. I also wonder if people are holding out for the black Wii.
Heavy Rain is surprising, but maybe not. There weren't any TV ads, but there sure was a lot of Internet exposure, including nude scenes (the nudity could have sold a few copies). I know people are on opposite sides of the fence regarding its short window of sales, but it wouldn't be unprecedented for it to sell more in March, depending on word-of-mouth. Infamous had about the same window of sales in its opening month, and went on to sell more in its second month, due to positive word-of-mouth. I'm still leaning toward lower sales for HR in March, though.
The sales split of Dante's Inferno is also surprising, since, as others have stated, GOW3 is coming out, shortly. It had a shitload of marketing, including a demo with nudity, also. Though, the demo actually cemented my decision to not purchase the game.
Bioshock is one of my favorite games of this gen, and I preordered BS2 for PS3, but there didn't seem to be anywhere near the amount of buzz for the second game as there was for the first one. Sure, the 360 version topped the software charts, but that's only because nothing else did amazing numbers, either. In fact, the next 6 entries all launched prior to February. Had I not played the first game, BS2 probably would've flown under my radar.
