thats not quite right, although games are region free, Blu-ray discs are not really.The PS3 games/blu-ray films are not regionally coded but DVD's and PS2 UK games wont work on a US PS3.
I paid about $670 for a PS3 back in December, brought it back and sold it for £600, but they be worth anywhere near that now as the UK ones are released shortly.

US Wii def won't work with UK games.
