My Sony is about 5 years old, but the picture quality is still really good. New sets will probably be slightly better, but the sources haven't really improved over this same period, so not sure it is a worthwhile upgrade (Although, if I had the cash I probably would). I'd say it's way too early for Ultra HD. For me, it will only be worth upgrading once there is a Sky Sports Ultra package... but I think we are a few years off this yet.
