I always preferred the 360 to the PS3, and now it's even more apparent because I own both.
The PS3 never gained the momentum Sony thought it would've, and Bluray discs haven't taken over the market as the next medium the same way of the VHS when DVDs came out and went mainstream. BRD holds less than 10% share of the market, they have to compete against PPV, Netflix, less expensive DVDs, upscaling DVD players, etc. The XBox 360 is still going strong after 5 years. The Wii is the overall leader in the marketplace, but their library is largely abysmal and full of shovelware, they don't move as many games as they should for leading the market. Even with top-titles like Madworld and Dead Space not generating anything, and their version of two year old CoD4 was an absolute trainwreck. It proves that the Wii isn't suited for games like this, and is a more family-friendly, casual audience. I hate using 'casual' but I don't know what else to use.
With the 360 and PS3 duking it out for the HD gamer market, and Sony lost a lot of users, publishers, and reputation with them taking far too long to deliver top titles. Not to mention third party titles are inferior and PSN can't compare to LIVE.
Sony said themselves that the PS3 will have a life of over 10 years. To be talking of it's successor less than 4 years in if they come out with a new one too soon spells disaster. Reminds me of when Sega was moving away from their consoles that were saturated into the market for newer ones, and gamers were pissed and felt betrayed and never forgave them.
