I will never leave Ableton 8. Period.
But I will buy the latest Abe to down-convert projects to 8 if this becomes possible.
I know one can export stems as a workaround - that's what I have people doing now. It creates a cold slab of audio with no warp markers, I'd much prefer to have some of the original loop and warping preserved. Warping didn't change much since 8...
