While i would like it to for many reasons, its just not going to for one reason. That reason? People are stupid. The vast majority of consumers want easy to lean guis, not cmd line, as even though cmd line offers many advantages, they wouldn't be able to use it. Its for this reason that linux is mostly used for stuff like servers, supercomputers etc instead of everyday consumer goods. As for DU on linux, NQ are focusing on making the game work and be fun right now, not spending a ton of time and resources that they are limited on to port it to linux. It may happen at some point in the future, but not now at all, especially as they said windows only.
