That list could also include Xbox Live and PSN. I'm willing to believe they will release the old games on modern digital services (although I don't trust DuvalMagic as far as he can be thrown) but I struggle to see a future iteration that doesn't include consoles in some way.
Porting a PC RTS to console doesn't make any sense. The genre is a proven failure on consoles and if you want to have any chance of succeeding, you have to build the game from the ground up for consoles. Even then, you'll likely fail unless you have a popular console IP attached (like Halo Wars).
We're more likely to see new Homeworld games on mobile platforms instead of consoles.
