Chances of a 64gb new Nexus 10?

What are the chances of a 64gb Nexus 10 popping up these next few weeks (months)? Do you guys think they will go that high or stick to a 16gb, 32gb setup? While I would love a 64gb version, I'm not terribly optimistic. Has there been any rumors otherwise? I remember there being some Best Buy leaks of there inventory but I can't find or remember what it was saying.
