The new Q-7 will be in Q-mount (of course) but will incorporate a larger 1/1.7" sensor, source of "leaked" information from the Japanese Digicame-info.com (Google-translated), which should be reliable enough for their past track records.
Btw, the Q-mount actually could accommodate a 1/1.7" sensor, yet with the possibility of the in-body SR, see my previous illustration below:-

So, what will happen with the original Q lenses then? Well, suppose the image circle is large enough to cover, the 01 "standard prime" lens will become a 35mm standard wide (135 film wise) and the 02 "standard zoom" will become a 21-63mm lens, which I don't think the image circle is large enough for the wide side. Thus, that explains why we saw a new standard zoom patent from Pentax Ricoh before, with a 1/1.7" image circle, details here.

you are frequently referring to Pentax patents when it comes to lenses and the roadmap. I have a question about this: how come that it is possible at all, hundreds of years after the first lens was assembled, that there are still "inventions" with each and every new lens? Shouldn't the field be completely out-invented by now? I'm puzzled.
Best,
Chris
