I am on a pre-release server and got in tonight without a queue, last night it was 10 min. Not bad. mini patch today sposed to have cleared up a few issues. So far game is fun. You can play it pretty solo if you want, just find a nearbye group for "heroic" areas and the flashpoints when you get around to it.
8 story lines to play though- so good for 4 months or so depending on your playtime.
