Use a shimano or whatever you want. I've even used a centaur triple with a shimano double bike.
It's going to be hard to have backwards compatible rings for red so I would guess from the top down the new "rings" will come with new groupsets for force, rival and apex that incorporate the same ideas for red making them NOT backwards compatible for old sram cranks.
The yaw thing is yet another gimmick to get rid of trim.
Did you read the articles? One of them claims that the FD with yaw can use all 20 gears without dragging the chain. You seem to either be ignoring the technology, disbelieving it until more information is available (maybe hands-on usage?), or unaware of it and simply talking smack from an uninformed position.
You're entitled to your opinions, but I don't want to be painted as a fanboy. I have high hopes for this technology based on reading about it, not because I think SRAM is just innately better than anything else.
