Despite previous announcements and promises there is still not a single glimpse (afaik) on AMD's Mantle-API publicly available. Will this be another notch in AMD's track-record of screw-ups? Will they wait (again) too long and let their lead be taken away by their competitors? Are they withholding as long as possible, to give OpenGL, DirectX/WGF or worse a yet to know new proprietary NVIDIA-API enough time to allow Mantle to become AMD's Glide?
