Was the move to Python 2.0 as big a deal?

IIRC, yes, it was. People have continued to use Python 1.5.2 afterwards
for several years.

The changes were significantly smaller, so the transition was smoother.

People will continue to use 2.x for several years certainly.

A year or two won't be sufficient. IMO, the resistance is due to the
feeling "it will cause me efforts to change my code, and I don't like
additional efforts". This is a reasonable point to take, IMO, so people
who have the time and inclination to convert their code will do so,
and many others won't. Over time, people will convert the code when they
do have the time (or the feeling that they shouldn't push it away
further). Eventually, those people will convert that need some kind of
library (change) that is only available for 3.x.
