Slant Six, developer of Resident Evil: Operation Raccoon City, was rumored to be working on Star Wars: Battlefront Online before being hit with layoffs in April 2010 (not to be confused with the studio's layoffs from June of this year). The rumored project was canceled, and leaked concept art pieces supposedly from that game were recently found by Siliconera, such as the one seen above, which can be seen at the source link below.

While it's nice to look at what could have been, Slant Six ultimately survived and launched free-to-play and Activision Mobile-published iOS game The Bowling Dead in late November this year.
