Obsidian and Gearbox Swapping Alien Assets

Since we haven't had an Aliens-related newsbit for awhile, I thought I'd mention that Obsidian's J.E. Sawyer has confirmed that there is a little asset-swapping going on between them and Gearbox Software.
So, since Sega is publishing both games, and since Gearbox is supposed to be releasing in the winter, I believe (though nothing at E3, I think), how much contact does Obsidian have with Gearbox, or with Sega about the Gearbox title?

We have coordinated our storylines and there are a few references between the two plots (including characters). We have also shared a few art assets when prudent.

So does that mean you've collaborated with the BSG scribes they've snagged for their game?

No. Pretty much all of our coordination was done at a high level (major plot and character points) before they were involved.

As long as these types of exchanges keep the two games from being completely different animals, Obsidian should be able to ride Gearbox's success (or failure!) with Aliens: Colonial Marines.
