Just spoke to my local tesco to try and find out how many PS4s will be avalable tonight. All they would say is that they have very limited numbers and that they have had lots of people ringing up asking about them. I'm not going to bother, I don't want to queue up for ages and sounds like they don't have a lot of them anyway.
I'm going to stick with my original plan of attempting to get one from John Lewis.

Saves queuing.
