i dont know about roundmaps but what might be in the next version
i guess depends largly on what volunteers do (spec, implementation
and testing wise)
support for bayer "pixel" formats and maybe paletted formats could
be in it. Some compression improvments by using inter frame prediction
would be an idea too. But i think 2016-sep is too soon for complex
additions like inter frames. All these things require trying multiple
solutions and testing/evaluating how they perform comression, speed
and complexity wise to see what makes sense to add to the spec
