I wouldn't bet on it

Eventually all of them.

Well I don't have insight in the mind of the core developers, but I 
think you could compare it with any other major software upgrade.
Think of it like people upgrading from windows NT4 to 2000, some 
software works some not, some people are happy with NT4 others prefer to 
keep up with current technology. Look at it like py3 is 2000 before the 
first service pack, internally it works, could need some polishing but 
that's about it. The things that don't work are more often caused by 
third parties then the core development.

If you want to be more on the safe side, I would say wait for 3.2 or 
even 3.3 . More specific, wait till the external module developers (the 
ones you use) say it is stable on Py3
