Don't know if they will be available, but there is a tab for add-on content, whether that means only official add-ons or modded add-ons too is yet to be known. I think if they did allow mods, they would have some sort of limit to how powerful you can make armor or weapons, being that everything is pretty much scaled in ESO. We can't have overpowered characters on an MMO. That wouldn't be much fun...or fair.

I wouldn't mind seeing some armor and weapon mods though. Something that looks different from everyone elses weapons and armor.
