While I think the 720 comment was facetious at best, those numbers you posted are actually not all that good for Microsoft.
The XBox to date has sold around 13.8 million consoles in the US. The PS3 is only around 6.5. The Wii has sold 14.2 or so. So, relative percentage wise lets look at some of the claims you quoted:
Xbox 360 “Call of Duty 4: Modern Warfare” (Activision) was the best-selling console game across all platforms, outselling the PlayStation 3 version by 2:1. (February NPD data)
You mean - exactly like it should have given the install base? That means the attach ratio is similar on both consoles. This type of statement only remains a selling point if the XBox can maintain a large lead over the PS3. If that lead starts to shrink, the ratio shrinks as well.
Xbox 360 has the top selling games on its platform. According to February NPD, Xbox 360 sold $184 million in games, with PS3 selling $97 million and Wii $130 million.
If I were Microsoft, I would have kept this number to myself. Even though they outnumber the PS3 approximately 2.2:1, they still only managed a 1.9:1 sales lead in software. I know they are trying to spin the absolute "bigger is better" - but once again if the PS3 starts showing large sales margins over the XBox this type of number is not good for Microsoft.
Third party partners find more success on Xbox 360. In February, Xbox 360 accounted for $159 million of all third party game sales this generation, or 45 percent of share. (February NPD data)
The XBox represents approximately 38% of the market, so this number is good right?
I actually seriously doubt it given everything else I've heard about third party sales on the Wii. I would expect them to be under 20% of total market share. That means the PS3 would have 35% of third party sales. Once again, if it has an install base of less than half the size of the XBox, you would expect its third party sales to be no more than 22.5%. Basically you have to ask yourself if you believe that the Wii is generating more than 32.5% of third party sales. This number is only good for Microsoft if you believe that they are.
No offense, but this is why I hate the NPD numbers. Both sides come out as their pure fan boy selves at this time with little regard for actually analyzing the numbers. I have said this many times, but the only people disappointed by these numbers are random posters on forums like this.
Sony is happy because their next gen system is finally starting to show some legs. they have established their format as the heir apparent in the physical media side of things, and their previous gen system (the PS2) is still selling extremely well. Microsoft is happy because they have successfully managed to obtain a portion of the console market and their console is finally profitable. Nintendo is happy because their systems are still printing money for them. Like it or not, no one is losing the "console war" that forum goers are so vividly following. I seriously doubt any of the three is disappointed at this point.
