This was already going to be a tough sell with major publishers. If Google isn't willing to promise they'll keep it around for a couple years, it simply won't be worthwhile for publishers to invest the engineering (and legal resources) to do these deals and the integrations. I don't expect this latest incarnation to gain traction in its current form. I do have hope for this subscription model still. If Google or someone else makes a serious go of it, I'll be cheering them on.
