I think they are coding for 12.5 already. They are just taking it as it comes, but these guys have ideas that they want out there. They just don't have them finished. Some things may show up in JB and some in KLP. Other may not show up until they get to S or T.
We may not even see JB on phones this year. It may just be on a Tablet for a while and not show up to phones until this fall. At that time we may also see a bunch of phones getting upgraded to it.
this made my head hurt lol
