Wouldn't be in the least surprised for Homeworld to turn up here. Maybe not a sequel though. By and large people seem to be confusing Gearbox itself with 2k and Sega, who are clearly big steam fans and published DNF/ BL2/ ACM. Pitchford's own view on the matter, albeit being from a while ago, was a lot more... flexible
"MPC: So you think Valve should spin off Steam?
RP: They should! It would be much better if Steam was its own business. There’s so much conflict of interest there that it’s horrid. It’s actually really, really dangerous for the rest of the industry to allow Valve to win.
I love Valve games, and I do business with the company. But, I’m just saying, Steam isn’t the answer. Steam helps us as customers, but it’s also a money grab, and Valve is exploiting a lot of people in a way that’s not totally fair. Valve is taking a larger share than it should for the service its providing. It’s exploiting a lot of small guys. For us big guys, we’re going to sell the units and it will be fine." Source
