...this isn't a "Oh I want this game on here" post, which will immediately incur a rash of "Check out the wishlist" posts...I just want to know if there is anyone more knowledgeable about this than I am.
I would really love if GOG released Homeworld, Homeworld: Cataclysm, and possibly, Homeworld 2. Now I know we just got (Dang it the name just slipped my mind...AAAARRRGGGHHH...that publisher) which (so I've heard) has the rights to sierra games? Since all these are sierra is there a better chance of getting one of these, than say, an EA game?
So does anybody out there have definite info on this? If so thanks! If not, I guess we'll just let this post die out with all the other "I want this game"/"Wishlist" posts

You could have just said "Who owns Homeworld?"
I think it would probably be THQ.

Well, Activision owns the old Sierra IPs, but I don't know about Homeworld specifically, it may have been sold before that or something.

Yeah, it's THQ. It followed along with Relic.

LOL! But that would have been too simple! :P
So in other words we don't currently have the people on board that we need to to get Homeworld?

No. But I see no significant barriers to getting THQ on GOG, to be honest.

THQ should be a no-brainer, but then every company should be for games sitting in a file somewhere making no money you would think. Corporations move slow as hell, that's one of their major downsides. THQ could start thinking about selling on GOG today and it could take 2 years before it happens.
Plus I bet GOG's region free, DRM free and rigid pricing structures turn off a lot of companies. Personally I only care about the DRM free part. but I know others disagree.

Nah I think you will find the majority will agree that if GOG is to grow then it needs a more flexible pricing policy. Even if that means games exceeding $9.99 (and lets face it we all know EA will want to charge at least $14.99 for System Shock 2) the price can always be countered with weekend deals.
Region restrictions are just another form of DRM though and have absolutely no place being on GOG.

Well, with no real DRM they could be easily bypassed of course. I'm not for enforcing those restrictions in any way, just in the fine print or whatever.
