Where did you hear this?

Remember they said that Xbox One would get more powerful over time.

I do agree that DX11 will be the norm, but seeing that the PS4 only does mantle and DX11, and is the better selling console, I think that will set presidence over which will be used. Plus no news from gpu firms on DX12.

I really dont see how it matters if DirectX12 comes to XBO or not?

Consoles will reach there limits pretty soon regardless.

The Xbox One gpu can hardly take full advantage of DirectX11 nevermind 12. It took quite a while before 11 was widely used on PC's..and considering how weak the console gpu's are its gonna take even longer for 12 to get adopted.

Well, I do hope DX11 is more used than 12 as I won't have to upgrade my OS to keep playing.

As for GPUs, I will depend on MSoft. If DX12 is basically a new API without new hardware requirements then there won't be a problem. If it demands some hardware tweaks, then they would have had to tell AMD and Nvidia about them with enough time to allow those changes to be added into their designs. And I think MSoft is still smart enough to have done it.

Yeah it would make sense, as much gamer rip on Microsoft, they where the one that help boosted the western game development thanks to the popularity of the DirectX engine. If this engine is even more dev friendly then the Unreal Engine 4, this could boost Windows 8 and PC gaming numbers.

Plus, they made some great games like Age of Mythology, MechWarrior, Kinect Adventures, Crackdown, etc.  People forget Bill Gates himself wrote code some games.

Correct me if I am wrong, but doesn't Unreal Enginge 4 run on top of DirectX? (and OpenGL, etc.)  It might allow them to make it better though.

You are wrong to assume that new DX brings new features and thus requires more resources. This was case with previous versions of DX, but DX12 is all about low level implementation of same features. In other words, it allows devs to use same resources of gpu in much efficient way, similar to Mantle. Sony has always allowed devs to have low-level access to gpu, while MS has not, forcing use of DX with it's constaints. So this could bring nice perfomance improvements and much more freedom to optimise.

PS4 don't use DX at all, DX is MS proprietary. PS3 and PS4 use OpenGL, as well as low-level apis.

DX is not an engine, it's a way for engine to speak with hardware. Everything on Xbox uses DX, UE too, because that's only way to program GPU on MS consoles.  New DX will allow all future engines to be more efficient on same hardware.

oh so DX12 wont bring new features that requires more resources :) ? Pretty sure it will.

Also considering that the X1 is a console, devs were always going to push the hardware with or without DX12. Perhaps the only thing DX12 does is speed up that process.

Although my initial post was looking at things as whole and not as of right now.

even though i wont be understanding most of the things going on, this will be very interesting.
