The development and release of ESO will not alter the release of single player games, since ESO is being made by ZOS, not Bethesda, Fallout 4 seems like the only thing delaying another single player ES game.
But yes, ESO seems to be coming along nicely.
Skyrim made tonnes of money so they will make TES: VI, Likely it will be a few more years since Bethesda is likely making Fallout 4 first.
From what I understand, TES VI is in the works already. But if you want something sooner, try the EARLIER TES games Morrowind (and even more, the games previous to it) are a bit dated in terms of graphics, but I think Oblivion holds up fairly well. (Although Morrowind was a better game IMO )
As for the internet hating change, that is true but on the other hand the community on a forum dedicated to a particular thing tend to be strongly biased in favor of that thing This is particularly true before release. Most people here are here because they are looking forward to ESO.
Don't expect TES6 for another 4-5 years at least. Fallout 4 is in the works but even that is nowhere near of being released so...
