The current round is far from over. There are nearly 700 gTLDs
currently in the root, and about 600 more names with applications
still in process.  There are still 8 names with pending auctions among
multiple applicants, and 21 that are "on hold" for various reasons.
This last group includes .corp, .home, and .mail.

DBOUND is indeed trying to come up with something less bad than the current
PSL, but ...

Sorry, that's just wrong.  DBOUND has nothing whatsoever to do with
zone cuts or reserved names.  There's plenty of ambiguity about what
we're trying to do, but neither of those are on or even near the table.
