WoW was 2 months from release to the first Onyxia kill. Slightly less than that for the first few bosses in Molten Core going down.
Are we a week past launch and the released content has already been beaten?
You can't directly compare SWTOR to the release of WoW in 2004. "Hardcore" raiding was an alien concept to everyone but the most diehard EQ fans in 2004. Now, thanks to 7 years of training in WoW, there is a subset of SWTOR players who made it their business to level to 50 as fast as humanly possible and beat the content.
Aside from putting up hard barriers to block access to the content (Sunwell-style) or putting in ridiculous gear-checks, there's not a whole lot they can do to stop them. I would wait and see if the content they put forward post-release is just as easy.
PS: The hardest part of Molten Core and Onyxia was getting 40 people together that didn't drool on their keyboard. Hindsight is 20/20, and there was nothing remotely difficult about any of the encounters in Molten Core or Onyxia. Raiding was just new to the overwhelming majority of WoW players at that time.
