Polish retailer Empik leaked what it claimed to be pre-order information and box art for Star Wars: The Old Republic earlier today, before subsequently pulling the offending listing.
A pre-order incentive of a "colour stone to change your weapon effect," was listed, and the box art is still up as of this post.
BioWare is set to make announcements regarding SWTOR this week at Comic-Con, specifically at 3.30pm PST/6.30pm EST on Thursday, July 21.
Maybe more light will be shed on pre-orders, and a release date then. Maybe.
