Do you think they are going to introduce an image stabilized version? Or is it just short supply?
Places that have it, have it. Here in Japan it's in constant supply. And No, they won't introduce an IS version (my opinion).
The new Leica D Vario-Elmarit 14-50mm/F2.8-3.5 lens
announced at PMA will have IS, and the new "E-3" body (supposedly to be announced later in summer) might
have in-body IS, but no one knows for sure.
