Spark Unlimited has a job posting for a "Senior Combat Designer" position that PlayStation LifeStyle thinks may be for Star Wars Battlefront III (thanks Gamer's Hell). They piece together other tidbits suggesting a new Battlefront game is in the works using the Unreal engine, and here's the description that helped them draw this conclusion:

Spark is looking for a senior combat designer for a 3rd Person Action/Adventure sequel in a high-profile science fiction franchise currently greenlit for full production development for Xbox 360, PS3 and PC markets. The Senior Combat Designer will be responsible for collaborating on developing game design systems, AI behaviors, player mechanics, and game balancing, tuning and timing for a third-person action shooter on current-gen consoles.
