No.
I'm running what is almost certainly my final campaign with my current group, and I have neither the time nor, honestly, the inclination to go find another group. So it may well be my final campaign ever. And with no game running, nor any prospect of one, there's no reason to buy (and so no chance of adoption).
If WotC were to publish the books in PDF, I would buy sight-unseen. But that's obviously not going to happen, and I electronic formats other than PDF are of no use to me. (I appreciate that some of those formats are almost certainly 'better' than PDF. But a less good format I can actually use is worth more to me than even a perfect one that I can't.)
