I also very much dislike shipping only python2. Having only one python
is admirable and I'm all for it but if we only ship one by default it
should be python3.

Fedora's next release is going to ship only python3 in all their media
(livecd, default install etc). Of course they will allow python2 to be
installed too but that will have to be a concious choice by the user.

I think the change next weekend should be as originally stated and have
2_7,3_4. Later on (perhaps we can see how fedora manages) we can see if
dropping 2_7 from the default stages would be doable.
