Not right now (I would like to wait for the remaining of the OCaml team,
and the release team approvals), but certainly before the 25th of June.
I guess there will be a lot of binNMUs (at least 50, maybe 100, out of
139 packages or so), and I don't know either how Ubuntu manages this
kind of task.

I think it's up to the Ubuntu release managers to decide. FYI, the last
transition (to 3.11.0) took 1.5 months since the first upload to
unstable, but it was a big transition: a new major version of OCaml, and
big changes in our way to do things that caused > 100 sourceful uploads.
The feature freeze for Karmic is set at the end of August, so 2.5 months
from now. So it looks like there is time, but rebuilds must be handled
efficiently (this is still an unknown to me). If you decide not to ship
3.11.1, care must be taken to not import ocaml 3.11.1 from sid.
