I very much doubt that the live chat hosts know what is really happening. I had this same issue when i expressed an interest in the Lumia 900 which was the flagship WP8 device spring of last year.
Carphonewarehouse and Phones4u advertised it as being available for pre-order on an O2 contract but when the time came they could fulfill all pre-orders on orange and vodaphone but were unable to for O2.
They were asked repeatedly what the problem was and could only reply with "O2 are currently performing network compatibility tests..."
So i then decided to come over here and visit our beloved O2 "service" provider who had not even the slightest hint of the device on there website but had been repreatedly asked on numerous occasions where they stood with respect to offering the flagship WP8 handset.
For the most part O2 remained mute on the subject but occasionally a O2 representative would offer some attempt at a customer communication and give hope to those and say "yes it will be available" and then some other representative would come along and quash all hope with a big fat NO.
I asked O2UK on twitter a number of times who simply stated "keep an eye out on our website for future updates" which was completely sidestepping the question.
So finally on to O2 webchat - they pretty much came up with "not sure dont know, keep and eye on the 'coming soon' list"
So all in all O2 is a telecoms company who either cant or dont want to comunicate with their customers through complete ineptitude or fear of loosing them to the competion.
