Originally posted by JPT Ricoh is good at advanced compacts and Pentax is not, unless you consider the Q.Pentac is good at ILCs and Ricoh is not. That's why the merger made sense. Ricoh will likely release more compacts and leave the ILCs to Pentax. Here are some possibilities.
A GR Digital with a larger sensor
A revival of the GX series of zoom compacts (built-in EVF? That would be nice.)
A monochrome camera (there have been some hints about this, but a long time ago)
Continuation of the CX series of travel cameras
I don't know what they are going to with the GXR, but shops in Japan were further discounting the body and most units just before Christmas. Either they're going to renew it or not pursue it any further.
Whatever Ricoh does, it will probably be photographer friendly and well made. What they could learn from Pentax is how to make their sensors perform better at high ISO.
Ricoh at one time had a few cult cameras for street photographers, I believe. Daido Moriyama used a GX200 (among different brands). I too wonder if a new GX X00 series cam, a cracking good and very solidly made high-end compact with a 1" sensor, might be a possibility. And that way, Pentax Ricoh can get something into position for when the Q series starts to run out of steam (due, imho, to its small sensor) - I don't think lack of interchangeable lenses is much of a drawback for a compact, especially if there is a sharp 24-70 or 24-105ish lens on it.
