I'm all for AMD going open source with these tools (I love the fact they're doing this) but the reason that developers go with GameWorks in the first place is because Nvidia is able to allocate staff/resources to the game studios to assist in implementing.
One thing I think Apple should do is to license Nvidia's GPU for their SoC. Especially when Maxwell is ready for mobile.
Nvidia clearly wants to license it out and I think Apple would be the best one to take advantage of it. Apple seems to be pushing the GPU side of their SoCs quite a bit.
Apps are definitely coming, I can't speak for other companies but for our app we're starting a private beta very soon and the launch/announcement is set for early next year.
