Are either of you able to confirm that the 950 XL is not coming to O2?
That is correct. Currently there are no plans to range this device but would always recommend you register your interest in ‘Windows Phone’ devices here, should this position change in the future: https://www.o2.co.uk/getupdates

Of course in UK just because a carrier does not offer a device directly does not mean its not possible to get it subsidized on their network. Carphone Warehouse is happy to sell the handset unlocked on Vodafone, O2 and EE at prices starting from £29.99.
