I think this is really exciting news. They seem to have finally understood the importance of marketing especially on social media.
I have the feeling that Ricoh will actually get out of the camera business.
But not as a company but with only their brand name and thereby push the Pentax brand.
Theta will probably be a brand/ecosystem on its own but how about a Pentax GR? Recent GR rumors (questionable source, I know) have suggested this might actually happen. From a business standpoint it would make sense to not sell cameras under two different brands and the GR would be a perfect addition to the Pentax lineup.
