Origin is now allowing preloads of the Star Wars Battlefront beta client to prepare for tomorrow's launch of open beta testing of the Star Wars action game (thanks DSOGaming). To download you will need an Origin account, and the client is around 10 GB. Here's word on the testing from a couple of weeks ago:

Get ready to be taken to a galaxy far, far away! Today, we are happy to reveal that the Star Wars™ Battlefront™ Beta will be available for PlayStation®4, Xbox One and on PC via Origin for players between October 8 and October 12. The Star Wars Battlefront Beta is a technical test and will give Rebels and Imperials alike just a small taste of the Star Wars™ battle fantasies you can expect to live out when the game launches on November 17.
