I can now confirm via multiple sources that Sony is set to increase the price in the whole Eurozone area (including UK). One of the sources added an interesting note:
Due to exchange rate movements almost all camera products will increase in price by around 10%. However the August date for the increase may not be so true as Sony are trying to wait for the competition to raise there prices first. It seems that Sony don’t want to be seen as the bad company that started it. So now it is like a poker game to see which company will show their hand first.
