New sensor had been developed as APS-C sensor by 4 companies: Trans Chip Ltd. (Israel) - already sold to Samsung, Samsung, Pentax and unknown 4rd - rumors - Sanyo, Casio, Cypress or Sharp (no true information).
All DA and DA* lenses are not developed to work with APS-H.
Canon had started to use 1.3 when FF had very high price and Canon makes now only 1 camera with such crop-factor for reporters. With very high price, although Canon is manufacturer of their own sensor. Leica uses Kodak sensor. It's too expensive to make and to use APS-H sensors. The price of APS-C sensor in production is very low now. And it's very profitable to sale APS-C DSLRs. How many users can buy APS-H camera from Pentax for 4000-5000 USD?
It's absolutely unreal situation for Pentax which work in the sector of DSLR under 1500 USD. A lot of DA lenses can't work at APS-H correctly.
There are no any rumors from insiders about new APS-H sensor. There is information about new APS-C sensor.
The 1.3x crop format will simply disappear in future. No good wide-angle and no good tele. Canon will offer new FF DSLR under $2000 USD and Nikon will make less expensive version of D3. No place for APS-H. To make APS-H sensor is expensive for manufacturer. It's simply as day. Canon and Nikon make the main money in DSLR market selling cameras with price under $1500. The best-sellers are not Mark EOS-1DMII/III.
)) They keep very small niche.
