We (Fedora) are step ahead. Currently we are waiting for a last few packages to be ported (anaconda is already running on python3 and ready for Fedora 23 release). Ironically the hardest part isn't porting (we've sent a huge amount of patches to upstream projects) but getting upstreams to accept the python3 as supported interpreter ("what is this python3 thing?" yes, this is a real quote). I am happy to see a new distros joinning a party, gl!
