There's no reason to say that ESO will be the last, or the last for a long time. ESO isn't made by the TES group. They are doing three things to keep it seperated from Bethesda. (1) It's not made by Bethesda, they're trying really hard at Zenimax to keep the TES feel, but it's not 'truly' a TES game. (2) They're setting it backwards 1000 years so that Bethesda can keep making TES games forward. (3) Finally, they're not calling it TES: Online, just ESO - or Elder Scrolls Online. That last point may seem small, but it's a huge deal. Marketing is everything, and those three things will help keep TES games going even if (and I think it's a big if) ESO flops out completely. But there's just enough hype to make people interested in ESO without overselling it to themselves.

That being said, I still believe it'll be a couple of years before we see TES: VI, but it's going to happen. In fact, I'd be willing to bet 10:1 they're already working on the preproduction bits.
