They've been gradually removing support for older Python 2.x with each release, so it's likely the same will happen with all of Python 2 in the coming years.
But that's probably a good thing. Python needs to keep improving, and Python 3 is just flat out a better language.
Isn't it still significantly slower? Even though it probably doesn't matter most of the time, it would helpful for all 3's items to be in the "better column."
The only significant slowness I've heard of was due to the I/O library, but it was only in 3.0, so has since been fixed. Or were you referring to something else?
