If you buy a PS3 in the UK (£475 with ONE game!) you better also put some money aside for the HD TV you will also need, other wise you could be looking at a blank screen! If you buy an HD TV make sure it's 1080p for the best image so in the UK that will mean another £1000+
Or stick with your Wii which will run on a £50 14" TV OR the 42" Plasma (if you have one) in the living room!!
