I had both consoles but the PS3 was my baby, the one thing that did it for me was the lack of Blu Ray on the Xbox. I love my films and because of the PS3 i have purchased a fair few Blu Rays.
Also my PS3 never made much noise, even after years of use. My Xbox was the nosiest thing ever at the time but the PS4 has blown that out the water.
This has to mean that they'll allow you to play PS3 games on your PS4, surely?
