Well the battlefield 4 integration keeps getting pushed back so who knows really. personally, i don't get why this is a big deal. I understand what it's suppose to do for performance, but there's a lot of problems. Not everyone uses amd hardware, so either mantle will have to support nvidia or developers still have to code everything in directx and openCL so it actually makes it more expensive to use. Secondly, like I said, not everyone uses AMD so it won't affect many people.
