According to the document spotted at Relic News forum, Homeworld's name has been passed from Vivendi to THQ. This might indicate that THQ might revive the RTS brand Homeworld.
Homeworld is a space themed, real-time strategy game developed by Relic Entertainment. As you might already know, THQ acquired Relic Entertainment developers sometimes in 2004 and made incredible success with games like Warhammer 40,000: Dawn of War and Company of Heroes series.
According to the Eurogamer.com THQ confirmed it owns the rights for the Homeworld brand, but they had no comment on any future games.
