THQ, publisher of the Red Faction series, recently registered a domain for Red Faction Battlegrounds. That, plus word the publisher is working on a Red Faction game for Xbox Live Arcade and PlayStation Network, equals a rumor.
The series' next title, Red Faction: Armageddon, is due out next year, and reports have the publisher cranking out a smaller-sized offering with no release date yet. But some also are speculating this could be the name of a Red Faction game for the Nintendo 3DS.
Of course, lots of publishers register tons of trademarks just to have 'em handy in case they like them down the line.
