All that realistically matters is what came out on Linux in the last 3 months, and what's upcoming on Linux.

The fact that there's going to be Linux powered Steam consoles coming out soon trumps anything that has happened up until now...

Not really. There are countless Android powered game consoles too but it hasn't exactly lead to an explosion in Android gaming.

Releasing hardware doesn't automatically lead to developers providing software. Linux still lacks 100% of triple-A titles not developed by Valve. What's upcoming is almost entirely indie ports.

Whether or not that is enough to start the cycle of shipping units, gaining more attention and seeing bigger titles dip their toes in the water remains to be seen. OS X had a decent advantage at launch, there were already smaller porting shops producing OS X ports of triple-A titles. Gaming on OS X was never popular, but it was there.

Valve is looking to pretty much single-handedly launch gaming on Linux. Nothing here is a trump card, everything is up in the air.
