When is the new minecraft pe update out!

Do you mean the 1.9 update? There's no set release date, as of yet. They're doing some major overhauls (combat system, for one) and performance improvements, which in turn necessitate having to do lots of bug-fixes. Hence the long wait :/ Sorry I couldn't be of more help, but no one really knows exactly. I'd 'guesstimate' based on the snapshot progression that it'll be out in 1- 3 months :)
