Combine that with what Michael's been saying and his past track record, I'm willing to wait and see. Denials from the VP are more of the typical soft one that actually denies little and sounds like they denied everything- typically told just to sidestep bad PR if it doesn't actually come together for whatever reasons. Something Epic probably should've learned a bit earlier... :D
Better logic would be: If Valve had no plans to release a Linux client, why would they do the work to put these Linux clauses in their scripts when they didn't intend to use them? Why would they use SH style scripts at all rather than some OSX binary launcher to get the job done? Why are LSB style binaries and libraries present in some of their newer games?
