Not really... for multiple reasons.
1) The technical one, is that all current MMOs are just evolutions of EverQuest. This is typical of 2nd gen, traditional MMOs. None of these are clones of another as much as a rock CD isn't a Beatles clone. Sure they have guitars, drums, sing, and use effects...buuut...not the same.
2) The aesthetic is not the same, no matter how many people want to claim it is. Being computer friendly and not realistic(TSW) or hyper/fantasy realistic(TERA, GW2) does not make it the same. They have a similar color palette, though Wildstar's is actually brighter.
3) Tab target doesn't make a game a WoW clone.
4) Design is a much larger concept than what you see on the surface and even what you see in combat mechanics. How endgame is structured and rewards are layered, combined with how they want to present everything to you is what distinguishes traditional 2nd gen MMOs the most in the long run.
