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.
I cannot for the life of me imagine this launching with any significant amount of content. Pretty much all the good stuff is already licensed to English publishers and getting a license for digital redistribution under a subscription model is not likely to look like a very good deal to most of them.
I still hope this turns out decent because more legal options are always appreciated but I fear they might just try to Sony-monopoly their way into a successful platform here.
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.
