I don't think anyone would ever claimed ESO was TES VI, since it's a spin-off MMO made by a different company (though all the spin-off games are still considered TES canon).

Plus Bethesda is working on Fallout 4, so we shouldn't expect a TES VI announcement until at least a few months after Fallout 4 launches in November.
