Under normal circumstances things move at a snail's pace within the Japan Basketball Association. So it's anyone's guess if talks between JBA officials and their bj-league counterparts will pick up anytime soon and/or if any progress will be made in the months to come for the creation of a new "top league" for 2013.
Based on what we already know about the leagues' recent history, there are few indicators that things are progressing in an orderly fashion, or progressing at all.
In fact, quite the opposite appears true.
