The people with solid facts don’t hang around on mailing lists like this, and would be fired if they responded. Apple does not comment on its plans. What we do know is this:
We have more than hints. Apple has steadily increased the incentives for third-party developers to drop 32-bit products. But it hasn’t even deprecated it, much less cut it off. Unless I had to accommodate a market (like education) that hangs onto hardware for a very long time, I’d never consider anything but 64 bits.
Apple itself has a harder decision, because it doesn’t want to break developers’ remaining 32-bit products. (Add the “Kind” column to Activity Monitor to see what I mean.)
All we can know is that deprecation will come no sooner than June (10.12 Tehachapi), withdrawal no sooner than June of 2017 (10.13 San Quentin).
