The PMA @ CES has passed, the next and more important event for displaying new products is the Japanese CP+, this is especially important for Pentax Ricoh as the new K-mount mirrorless should be announced there by that time:-

Well, unlike what happened at the CES, a quick search to the exhibitors reveals that Pentax Ricoh and Ricoh will have separate booths. So, this sounds better as the two brands should work independently. Btw, I am not really interested in those Ricoh products in particular the GXR.
