Hello,

Being somewhat pessimistic, I would say that chances are very small that 
sage will be fully python3 compliant by then. For the moment, only 2 or 3 
people are actively working on the problem. Erik and Jeroen have apparently 
turned their attention to other important matters. There remains on the one 
hand many small annoying issues to be taken care of one by one, and on the 
other some difficult large-scale issues ("round,ceil,floor in python 
semantics" and "graphs sort their vertices" and "modular symbols with 
another basis" to just name 3).

What we should do is just go on, and then sage will be as much compatible 
as we could. As I already said somewhere, help is welcome.

Frederic
