If you enjoyed Skyrim, you'll probably love this one even more.
Why do you say that? This game looks nothing like Skyrim. Unless you are being sarcastic?
To many if not most Elder Scrolls fans, as long as it's as close as possible to Skyrim but with other real people they will be extremely happy, because that's all we really want, if you go in thinking WoW killer or something like that, then yest it will be completely disappointing
But the thing is what makes Skyrim such an amazing game with so much longevity and replayability is that it can be modded. You can't mod an mmo, not like you can with Skyrim with user created content adding new weapons, armor, areas, quests, and all that goodness.
I think people will buy this expecting Skyrim 2.0 and be severely disappointed when they don't get it.
