id Software's John Carmack has often commented that his engines target a particular feature set of a graphics board and he uses a certain boards for his primary development; for instance the Doom3 engine was initially targeted towards the features enabled by the GeForce 256 series of graphics processors, but overtime that was incremented to DirectX8 and 9 level boards, with NVIDIA's 5800 (NV30) being his primary development platform for a while. What has always been clear is that the PC, and the capabilities of PC graphics, was id's primary target market and development platform. From John's keynote speech, transcribed here by Beyond3D forum member aaaaa00, it would appear that this is likely to change, in the interim at least:

In the last couple weeks I actually have started working on an XBOX 360. Most of the upcoming graphics development work will be starting on that initially. It’s worth going into the reasons for that decision on there. To be clear, the PC platform will be released at least at the same time if not earlier than any of the consoles but we are putting a good deal more effort towards making sure that the development process goes smoothly onto them.
