The @BlackBerryDev twitter account has revealed that the Native SDK is coming to Linux.  In a tweet to @alketbihamad, RIM confirmed that the Linux version should be arriving with the third Beta version of the SDK, right before the Gold version.  This is welcome news as RIM focuses on catering to the needs of developers in order to bring apps to the new BlackBerry 10 platform.

This is contrary to developer tools on other platforms, such as iOS, which are exclusive to OS X on a Mac.
