Am I totally wrong when I think that 2.6 should be 100% backward
compatible with 2.5 (unless explicitly requested in the python
script itself and even then it should just emit
DepreceatedWarnings)?

Python will contain some forward 3.0 compability, i have not read any
thing about 100% backwards compatibility.
http://www.python.org/dev/peps/pep-3000/
but even if it is, then you will have to do a
a python 2.5 to python 2.6 with (__future__) features to use some of the
new stuff.
and later you have to do a 2.6 with (__future__) features to python 3.0,
because as they state in then pep-3000
<snip>
There is no requirement that Python 2.6 code will run unmodified on
Python 3.0
