1.3.4, actually :-)

neither.  netbsd-current and netbsd releases are 2 different things. the
tree looks something like this:

mainline tree 
   ... -> 1.2H -> 1.3A -> 1.3B -> 1.3C -> ... -> 1.3I -> ...
               \ 1.3 release branch
                 1.3 -> 1.3.1 -> 1.3.2 -> 1.3.3
there were similar release branches for previous releases (1.1, 1.2, etc).
when the 1.2-current mainline reached a point where the "required"
features and stability were available, the mainline tree was branched and
called 1.3.  after enough pounding on the branch was done, the 1.3 branch
was released.  however, development continued on the mainline branch
during the time the 1.3 branch was being tested (this is why the first
1.3-current version was 1.3B, i think).  from time to time, when enough
bugfixes and other useful patches are accumulated against the release
branch, then a new patch release is made.  this is what 1.3.[1-3] are.  in
general, no new major functionality is included in a patch release
(sometimes drivers are backported, but something like UVM will not be).
when the powers that be have decided that the 1.3-current trunk has the
required features and stability, it will be branched for 1.4.

there have been discussions on doing this (making 1.4 be 2.0), but i think
most people just have a hard time dealing with the fact that other BSD's
are at a higher major revision number.  it's pretty meaningless, except
perhaps from a marketing point of view (but really, why is OpenBSD 2.x and
better than NetBSD 1.x?).

not really.  there has been some mention that kernel threads/smp support
will be the needed catalyst for the 2.0 version bump.

it doesn't sound stupid to me at all.
