Unlikely, JR are concentrating on DMSS at the moment and the next beast to put in an appearance will be the XG11. Then probably an XG9, I know they where looking at a 16 channel system some years ago but that seems to have been put on the back burner.
I doubt if JR are going to produce any new DSM based systems (that's JR Japan by the way).
But our Japanese friends do have a tendency to surprise us all every now and then.....
