The MMO market is so hard to crack if you are a newer game as lordofthereef says "Everyone compares is to WoW". The good thing about SWTOR is that they already have a huge following so integration should be easier.
Personally I can't wait as I am a recovering WoW addict and managed not to pick it up for nearly 6 months. True most nights I shake like a pooing dog but I am sure SWTOR will quence my needs. Roll on release date.
