Sorry to give such an unhelpful answer, but we haven't announced anything about future release plans or features yet.
It is a safe bet that as soon as we do have any information, that will appear on the XNA Team Blog, which is the place to watch for such announcements.
There is pretty much zero chance you will get any new information like this just by asking in the forums. The marketing people would kill us if we started disclosing random details of future product plans in such a haphazard way! :-)
