Several people reported this video by Gearbox where you can spot they're using Blender in the production of Homeworld 3!
Hi, as the title suggests, I was watching the Homeworld 3 Fig Announce video and, as usual, became curious as to what programs the devs were using. I paused the video to see, and, lo and behold! There is the lovely little Blender icon sitting on this artist's desktop! Sadly, his main screen is actually running, I think, Maya, but he's definitely got Blender there for when he wants to actually have some fun!
The best shot is at 4:55, but you can also spot a quick glimpse of the Blender icon in a dock at 4:17.
