Warcraft = hit its peak at TBC - despite ridiculous sales of WOLTK on release. It's only a downward spiral from now but it'll be gradual for a little while yet.

SWTOR = Pretty smart and well designed but I didn't find it that great or ground breaking. I imagine it would be fun and a little different to WoW but in the end its pretty much the same repetition.
It did _not_ up the anty against other MMO's inclusive of Warcraft.

Istaria is very singular in how it works as is the aging but equally beautiful Anarchy Online. It will appeal to a select audience who want slightly different things from a online hobby. Which you know what, actually makes people treasure it more so than a typical MMO. At least in AO/Istaria you can have beautiful & fun people but also a very charming game.
