PS3 is the higher quality system
PS3 will keep selling long after 360 is dead and gone. M$ is all about money and doesn't care about quality gaming experience. Once they are done with the 360 they'll do the same thing as the original, shut down the servers, stop servicing/producing the system and FORCE you to upgrade to the new expensive system.
PS3 has blu ray, better exclusvies, better controler, free online play and will be around for a long time to come. Heck they still sell 1.3 million PS2's every quarter! PS2 has sold more than 150 million systems! PS3 will get there, it's only 3.1 million away from 360 and the 360 had a 1 year head start.
