If you look at what happened with other major language changes
(Perl 4->5 for example) there is likely to be a lot of support
for 2.X Python for several years. This will likely be driven by 
necessity,
there is an awful lot of code out there that won't be upgraded to 3 
for
a long time. But new features will likely start to only appear in 3.
And 2.X releases will be focused on bug fixes etc.

There is a web page somewhere on the web site that gives a list
of the new features/improvements. None of them are totally compelling
for me but I am starting to look into it now.
