One thing that has not been mentioned is that once E: D got onto Steam there is a good chance it will be converted to run on SteamOS which is... (pause for effect) Linux.
It's actually a Debian derivative which for those of you who run Ubuntu will know works very well. With a Mac (UNIX) version the chances are high that it can come to Linux in time. However, I'd bet on Gabe doing it for the Steam Machines before then.
Here's a vid that explains it in part.

If you want to download SteamOS to play with it, you can get it here:

Damnit dude, it's not Deebian... It's Deb-Ian. It was named after Ian Murdock and his wife Deborah.
Ha, that goes right up there with people pronouncing it najios instead of nagios.
Anyhow justs because it's on Steam doesn't really mean it'll be on SteamOS. But I think it needs to be, there are obviously a lot of Elite fans on Linux, since a lot of the open source remakes have originated there. I'm just hoping that now that the Mac version is completed, they can work on the Linux version. Here's my crazy thoughts though... why would any company make a game for the Mac before Linux?
1) Macs generaly don't have exceptionally good hardware for gaming. Unless you're willing to spend a whole lot more money on one with an nvidia or amd chip in it, and even then they're not exactly high performing systems. There are of course the select few who buy Mac desktop systems, but I'm pretty sure most of them aren't hardcore gamers.
2) Pretty much most Linux systems on the other hand are the same systems gamers would use. Drivers are already there (I haven't checked yet, but I'm not even sure my Saitek x52 Pro works on the mac, I know my Roccat Keyboard and Mouse don't have Mac drivers, but they do have Linux ones.)

P.S. I figured I'd look it up real quick. Looks like the X52 Pro will work on the Mac, but none of the software for configuring the MFDs is available (they are within Debian's repositories, and they do work I've tested them there, and there are other utilities to change buttons around if need be.)
