This one is coming with a patch at least. Maybe it's some content or HK-51 or something awesome.
EDIT:
We will be performing an unscheduled maintenance this Thursday, July 26th, 2012. After the maintenance, there will not be a new patch to download.
The servers and SWTOR.com will be down for four hours on Thursday, July 26th, 2012 from 2AM CDT (12AM PDT/3AM EDT/8AM BST/9AM CEST/5PM AEST) until 6AM CDT (4AM PDT/7AM EDT/12PM BST/1PM CEST/9PM AEST). All game servers will be offline during this period. This maintenance is expected to take no more than four hours, but could be extended.
After the maintenance, please login via the launcher to download the latest patch. If your launcher was open during the maintenance, you must close and reopen it for a fresh login.
Well, the first part says there's no patch, but the last bit eludes to there being one to download...
DOUBLEEDIT:
The launcher says a patch is being deployed... *sigh* BioWare...
