My understanding is that the plan is for all Valve Source Engine games are going to be ported (and should be relatively simple now that TF2 is working).

Everything else is up to the various game studios, though all games in the Humble Indie Bundles support Linux so hopefully they are added to Steam soon.

Darn. This what I'm waiting for as most of my games are from humblebundle. Well at least uplink+defcon should work :)

uplink works. defcon doesn't, unless you some manual "patching" (download the demo, fire up defcon in wine/windows to get your steam key, activate it on linux). It'll eventually come though.

Many are already available.

My impression was that they started the project by porting Left4Dead, but decided to release TF2 (probably because it's F2P and so anyone can test it).

TF2 also has microtransactions so it will also earn them money in the short AND long run as well.

Quite a smart business decision and I'm glad they brought TF2 over - I always thought this would be the first game to publicly release.

It was also the first game they brought over for the mac port, though I think that was before the in-game store.

Wasn't that Portal, which I got for free at that time?
