Blu-ray gets more and more popular all the time
Sony is adding some very profitable projects to its fold like the PSPgo, and isn't wasting time with big huge make or break ones (that are at its mid-life like MS is doing with Natal).
And with the Slim, they cut the price to manufacture the PS3 probably by $50, while both got a $100 price cut. So, in essense Sony has more room to make a future price cut, if need be b/c MS hasn't achieved a similar manufacturing efficiency.
And to top it off, as sony's market share grows it will be able to command more advertising $$$ and sell more and more SW, eventually getting to the point where it tops MS in software long before they beat em on the HW side.
Sorry, but I wouldn't put your hopes on the 360 , MS has mismanaged that thing from the begining w/ the RROD and now Natal which just does not look like it will be worth the huge investment that MS will have to make for the project- not just R&D but paying the developers off-as well as all the money needed to produce , ship, and market the natal product. MS would have made a much better investment with its $$$$ by putting more into its online services or by investing in more games to just shove Sony out of the market but they really took the stupid approach and they'll get what they deserve for the idiocy.
Sorry, i'm blunt but try to be honest.
