A few lines about gameplay
A few small screenshots
And a handfull trailers

That´s all you can get if you check out the official Lucasarts Battlefront 2 website.

The SWBF1 website looks much more professional with lot of more informations about vehicles spaceships units weapons planet ect...

Compare them:

Be patient... More infos will come sooner or later...

Lucasarts has a tendency to keep games secretive until a couple of months before release. Then it will be a media flood. Plus, don't rely on the official site, they always put stuff up last. You get far more content by heading to a game news site. However right now they don't have much more then the official. But as Leviathan said, it will all come around sooner or later.
