hmmm, XBOX360 is king in the UK for now but I'm sure that the gap will close a bit like in America. I don't think that PS3 will ever catch up to the xbox in the UK and America but I think the gap will lessen. I think all xbox360 fanboys will at least agree to that. GT5, God of War III and God of War series pack, and Uncharted 2 will definitely move PS3 units.
The economy is sinking and unless you have a lot of expendable cash, I think a lot of people would be hard pressed to buy 2 HD consoles. If you don't like HALO or Uncharted, I mean, you could go either way. A lot of games are released on both consoles now.
