Im concerend about how much the old republic looks like WoW. I mean yeah sure, doing everything different just for the sake of being different is not a good idea. Especially considering how well WoW turned out. Don't fix what isn't broken right?
And I know all mmo's look somewhat the same since you know, they are the same genre.
But after months of bragging about how they put their typical bioware conversations into an mmo, they finally released some actual gameplay footage. And it looks so much like WoW I'm surprised blizzard hasn't sued yet.

Sure they may have added some unique ideas but THIS (getting quests from npc's, riding around on your mount and killing mobs) is what you WILL be doing most of the time. So it counts more than anything else.
