From the article:
Crunchyroll announced during Sony’s Consumer Electronics Show (CES) press conference on Monday that it will launch a new manga app named Crunchyroll Manga later this year as a premium add-on to its subscription service. The app will launch first in English in the United States and Canada, but other language options and web browser integration are planned.
There are definitely great manga out there that have digital subscriptions available in Japanese but not English. Skip and Loafer comes to mind, as well as Witch Hat Atelier.
