Gear Upgrade Vendor disappearing?

Green Armadilllo noticed that Blizzard is removing the Valor Point gear upgrade vendors on the PTR. Rohan isn't worried. He reckons that they'll be back in 5.3. Maybe they will and maybe they won't, but the sure thing is that you won't be able to upgrade any 5.2 gear, and 5.3 is when?, so if you're saving VP to upgrade your gear, now is as good a time as any to do it. Also bear in mind this blue comment:

we all know that even on live [servers] things can still change, so if a change is urgently needed, we do our best to apply it as fast as possible

Perhaps, having made the decision to get rid of the VP gear upgrades, Blizzard intends to remove them post-haste on live as well on the PTR. Perhaps in the next server reset? Probably not, but I'm not waiting around to find out, especially since there's no point in saving VPs to upgrade 5.2 gear. I'm upgrading my current gear tonight. Why not? We're bathing in Valor Points, thanks to Wrathion.
