Ça m'a intrigué et j'ai fait quelques recherches. Je peux me tromper mais à priori il y a une "rumeur" plutôt sérieuse qui tourne sur internet. Un dév de reliq aurait dit à un journaliste "tiens ça fait plaisir de revoir la franchise homeworld revenir à la maison". En combinant ça au fait qu'ils viennent de sortir du dév de la franchise dow et CoH, on peut penser que le dév de Homeworld 3 est une idée possible chez reliq. Bref wait & see mais ça se pourrait qu'ils essaient de surfer avec la vague de l'annonce du prochain X3 au niveau marketing & com. Extrait de l'article ci dessous.
"In November of that same year there was more news: Joystiq asked Jonny Ebbert, lead designer of Dawn of War II, about Homeworld 3.
"We're really happy the IP has made its way home, and yeah, we're definitely looking at it."
— Jonny Ebbert about Homeworld 3
Another reason for speculations for a possible Homeworld 3 was a Eurogamer visit in Relic studios published 24th November 08. In short: Relic has 3 or 4 teams working on different projects, we are aware of three teams: The Dawn of War II (including it's expansion Chaos Rising) team, the Space Marine team and a Company of Heroes team. Also Relic has not confirmed nor denied any possible work done on Homeworld 3, in fact employees are making indirect allusions about Homeworld 3.
Danny Bilson of THQ tweeted that Relic's next big RTS will be announced in August 2011"
