So I want to get the ps4 but I already have a ps3. If I buy I a ps4, I will be keeping my ps3 because I want to be able to continue to play ps3 games as well. How would I be able to have them both connected to the same TV? My TV only has one HDMI channel so would I be able to just plug in the system I want use each time or would it require more set up than that each time I switched between the systems? Or is there any other way to use both systems without buying a new TV?
