Given that Guido does not want double-digit minor version numbers, 3.9, 
at the latest, will be followed by 4.0.

There will be several deprecated items removed, such as
http://docs.python.org/2/library/unittest.html#deprecated-aliases
I think it would be worth making a consolidated list.

I think a few modules that have replacements will be considered for 
removal. Optparse (if argparse is an adequate replacement)? Asyncore (if 
the new async catches on)?  Changing the meaning of a core feature like 
float literals is a different matter.

3.5, ..., 3.9, 4.0 is 6 releases, which should be about 10 years.
