I don't think you understood me correctly. It's obvious no company wants to produce cards for mining (why would they?), AMD/ATI don't produce the cards, they design the chips and a reference card and that's it - they couldn't give a monkey's what manufacturers choose to do with their design.

So take the reference design => Cut out a load of stuff which isn't needed => Final result is a "mining" card with a much better MH/$.
