it has been reported on numerous sites that 3d capable tvs are needed for the 3d technology coming out for the ps3. the red/blue 3d of which you speak has been around since the 70's i believe.
no matter when it first came about it is still old technology. some games may include the option to display the 3d content in the manner that you wish, however it is more than likely that most games developed with 3d in mind will only use the shutter glasses technology.
new technology is always pushed for consumers to well, consume and buy, buy, buy. personally i am going to have to wait until i get a stable/secure job at a game developer to be able to afford anything above and beyond my current 32" 720p tv. also the fact that the 3d still requires glasses is keeping me from completely embracing the technology.
sony is pushing for the shutter glasses 3d technology. they even make their own shutter glasses.
