There are no plans for this I'm afraid - we'd always recommend registering details here "just in case" but as you're due an upgrade and we have no current plans for ranging the 64GB, you may need to consider options elsewhere if the 64GB model is what you need. You may still be able to get this on O2, but via a partner like Carphone Warehouse - they don't do Refresh though as thats exclusive to O2 direct.
Sorry for any disappointment

@Anonymous I've been very interested in this phone too, along with the Nexus 5X, but I'm holding off a while. This article may interest you. It's not the first one I've seen highlighting these possible problems.

been running a 6p since launch with no issues
not sure why 64gb is needed unless you have a lot of music locally stored
ive ran 32gb on nexus 5 nexus 6 and now 6p and have never come close to running out of space
if its photos then google photos now allows you to delete off device all backed up photos to free up space
re the problems that are all over the internet
not many people (me included) shout from the roof tops if their device is perfect only if there is a problem just be mindful any problems you encounter hardware related will be under warranty in theory anyway
