I expect we'll see a Albert Lamorisse disc with these two films timed to tie in with the release of Hou's Flight of the Red Balloon.
Maybe they'll even release Hou's film...
That part isn't likely. IFC Films picked up the North American distribution rights to the Hou.
This looks to be the next major theatrical release from Janus. Since it is no longer random speculation, but a relatively sure and imminent thing (and since posts can no longer be easily split off from this thread), I have created a new thread for the release here
