Techradar.com report that the Sony XEL-1 hit the UK market in 2009!

I'd be very surprised if this hasn't arrived in the UK by 2009," said Sony's Christian Brown. "We at Sony think this is the future."

There's no word on pricing for the UK as yet, but it costs $2,500 (£,1250) in the US and will likely retail for the same amount over here.

The interesting this is this set was unveiled as a kind of prototype for what could be when it came out in Japan. Rumours state Sony is making a loss on each set, as it attempts to show the world what OLEDs are all about.
