I think it's a longer term play.
Step 1) Establish a large enough non-windows userbase with great compatibility tools
Step 2) Studios and especially game engine developers notice linux install base
Step 3) Some tangible benefit to running natively, if only stability, pops up and the userbase is now large enough to care about it
Step 4) Engines, and then games get better native support

Also some anecdata from someone that pretty much bought all native linux releases from Steam since the linux version was released: in the past 2-3 years there were barely any new ones, outside of Valve's own titles maybe.
