Looks like the SWTOR queues are here to stay. Below are a few quotes from BioWare community Manager Stephen Ried.
“This is to be expected during launch, as a high number of people want to play the game, and for long stretches at a time."
“We’re monitoring all of our servers around the clock, and we’re raising server population caps where required. However, to ensure our long-term goals of server stability and healthy populations, we do not want to raise population caps too rapidly. We want incoming players to populate lower population servers. At the same time, higher population servers will not be ‘locked’ because we want to allow people to join a server to play with their friends if they wish to.
