If FO4 is any indication TESVI isn't going to look much like an RPG anymore. I guess they could take another turn in their design philosophy, but considering how much money FO4 made them I don't imagine they see any need to.
As for ESO it's actually pretty fun and the world feels genuinely Elder Scrollsy. I got it last summer and played through the thieves' guild storyline and promptly lost interest, but just recently started playing again and am fairly entertained. It's less immersive than a single player RPG, but the world is huge and it's nice to explore pre-TES Tamriel and you can play it perfectly fine as a single player game.
