GameIndustry.biz has published an article that summarizes Bill Gates' comments -interviewed by Dean Takahashi of the San Jose Mercury News, regarding how good the different strategies of the major console makers are doing so far, in his opinion of course.
As an indie, and from now on I will only refer to the 'game development' side of the story, I agree that the XBOX360 will do great since MS has decided to make the "development transition" easy for us: XNA.
I mean, the easier they make it for developers, the more developer's attention -and projects- they'll get, and ultimately, the more games will be created and released for their console.
If -in addition- "easy" includes "cheapper", the better.
Please do not misunderstand me, I'm not saying with this that console makers should make less restrictive the quality assurance policies and controls for commercial games. All I am saying is don't forget "indies", thus, help us produce for your consoles by providing better and affordable tools and frameworks, reducing the cost of game development (including time and effort as a "cost").
XNA GSE goes in that way, the right way imho ... ;)
