Ummm... Pretty sure that Nintendo has the number one machine, and, worldwide, PS3 has significantly outsold X360 for the same initial time period.
I have a great deal of respect for the X360 and think there are a ton of fun games, but Nintendo and Sony both have very significant hardware platforms which offer unique bang for the buck which Microsoft doesn't really touch.
If they offerred a 'cheaper' HD solution, it shouldn't come with the baggage of 30%+ failure rates. That ends up not being cheaper. If it's a step up from the Wii, then it shouldn't be so much more of a price jump for both hardware and software.
I think Microsoft has a lot to offer any gamer, but when it comes to new sales, they aren't offerring a platform which truly offers a unique experience nor a new experience as Nintendo and Sony are doing - and this is currently being reflected in their new console sales.
By the way, money taken in, Microsoft is ahead of the Wii.
I'm not exactly sure what Microsoft is going to do this year to push more sales of consoles, but by the end of last year, they had been bumed to number two by the Wii, and by the end of this year... maybe... the PS3 will be ahead - or far closer - in consoles sold than Microsoft.
I continue to hear almost no reports of failure from Wii or PS3, which is a very significant piece of fact. The PS2 was plagued with issues and was a poor DVD player. The PS3 is a solid piece of hardware with excellent build quality. The Wii is just fun, even if some games are really hokey with control.
