Moving to 3 would be a long way off - years+.

3 has a few interesting things for bzr;
Firstly, things like Pynie only run three - and it specifically claims
to be *much* faster at running code than CPython.
Secondly, If (I'm being generous :)) there are significant issues in
Python 3 that affect us, we stand a much better chance of having a
smooth transition if we file bugs - which requires us to actually
compile on the platform.
Lastly, eventually, Python 2 is going to fade away, and we should be
ready for the early stages of that, which is platforms such as Ubuntu
or RHEL that want to ship only Python 3, or Python 3 as default.

I'm not, nor do I think anyone was, talking about making installers in
Python 3 until it really is better for us. But right now its a big
unknown, and it would be nice to reduce the risk involved in getting
across it.
