When a game I'm interested in comes out, one of the first things I want to know is will it be SteamWorks. It's more than just a tool, it's almost a gaming platform in itself.
You could also stop harping on about piracy, it's not the cause of developers choosing to go cross platform rather than exclusive.
Well, if the topic is " Changing fortunes for PC gaming..??" one can not stop harping on about piracy because piracy is by very-very far the biggest problem of PC gaming compared to all other platforms.
And Steam is a non contributor as far as solving this MASSIVE problem goes. Checking releases, mates, patches is all well, but does that really change fortunes? I doubt it.
Why do we see even cross platform releases lagging more than a year behind consoles? Piracy. Why do we see few PC exclusives that could truly take advantage of the superior hardware? Piracy. Why more developers concentrate on multi-platforms with PC platform being at the bottom of priorities? Piracy. Why arcades dominate the market - because consoles are priority; why consoles are higher priority for devs? -PC piracy.
The only change in fortunes has happened in multiplayer, where piracy has little effect. Hence we see Starcraft, WoW and BF3 pouring big money into PC platform. Non multiplayer focused games are near impossible to develop for PC - as was always the case for the past 10 or so years. No change in fortunes there.
