We won't see any new books?
You sure? Publishers and retailers are going to turn their backs on millions of users just like that?
Me, I doubt it.
For now there is at least one commercial ebook publisher that is dropping 4-6 new ebooks in mobi, pdb, lrf, lit, and other allegedly dead formats.
And Calibre and Mobigen are out there allowing cration and conversion.
Several online ebook creation services also support mobi/prc/azw.
Mobi format isn't being retired; the format is alive and well. The only thing being retired is the traditional mobi *DRM*.
And that isn't relevant to DRM-free apps like coolreader.
Careful with the "standards" kool-aid; entire companies have died betting on "standards".
