Bethesda takes time with their games.
They will probably be working on Fallout 4.
TES isn't like fifa, cod and all those other crap 99% copy and paste games.
You have to keep in mind that Elder Scrolls Online wasn't made by Bethesda Game Studios, but by ZeniMax Online. As far as I know they were in contact in terms of lore etc, but other than they're independent form themselves, and Betehsda Game Studios is surely working on their nex title, probably Fallout 4.
Bethesda doesn't churn out game sequels every half a year or so, Fallout and TES sequels come out every 3-5 years. It takes a long time to make the worlds that they create, as well as getting used to the new software upgrades and new console limitations.
Their next game will probably be Fallout 4, as for the next TES? Give or take 3-4 years. I just hope they don't do a godamn contract with Microsoft or Sony again... Don't rush the next game!
As for the whole thread title? That's like comparing an apple to a cow...
Except for Battlefield and Grand Theft Auto.

M'aiq prefers Skyrim over Online.
Fallout 3 came in Autumn 2008.
Actually, Fallout 3 came out later than Oblivion, and New Vegas was developed by Obsidian, not the Bethesda themselves. But still, Fallout 4 is what they probably are working on.
M'aiq thinks it was released in 2009. He may be wrong though.
M'aiq agrees.
FNV was better than FO3 in many respects.
They are working on a new game. It's taking them longer than I expected to announce it, and they ended Skyrim content earlier than I'd hoped, but that probably has to do with the new consoles and maybe engine changes.
I do feel that TESO is wasted zots, but the people who like MMO's will disagree.
