I believe that many people have the wrong idea about Leica... IMO, Leica traditionally aims to offer the best IQ possible out of any manufacturer and it factors the assisting parameters (ergonomics, build quality, reliability, functionality) as high as no other maker. IMO, they try to price their equipment as low as possible, but -obviously- the quality parameters add to cost... The recent pricing policy on the S-series, is a proof of the above... They now offer better performance than ever at near half the price than when the product started its career...
There was a very difficult path for Leica to retain its values (offering the best IQ possible) with them being late into the digital market as there was a (new) parameter involved in which they had no experience at all during the film days... that being the sensor! However... they seem to work highly on the matter as to not only catch-up, but surely to beat the competition as soon as possible and this shows again with the later introductions (S series & Q)... Another proof is that they have stick into the 6μm pixel size in all their exclusive sensors, which (I believe) they won't abandon unless they reach the level of performance that worths the Leica name... But none can argue that the more their recent products are appreciated, the better their pricing becomes!
I believe that the new camera will have a sensor that will be very closely related to a cropped version of the S 007 series, which would mean that it would be among the best performing sensors in the FF market... As for the body pricing, I strongly believe that the build quality will justify it better than ever before and also that it can't be more than the Q (since it will have no lens) but it will be significantly less than the "M" series too (it being a "T"-series that is the introductory interchangeable lens series). Never the less, I believe that all the later Leica introductions will be of surprisingly high sensor performance from what people expect having older Leicas in mind and that the next generation of sensors will be second to none in the market. I believe that the rate they introduce new sensors one being better than the other is a proof of that and that this rate won't slow down soon...
As a conclusion, I am sure that they won't be satisfied unless their sensors are on par with the same level of quality that accompanies the rest of the parameters they offer in their cameras and that their pricing will become better and better, as their market section keeps expanding with out ever making a compromise in quality... it's the Leica tradition! ...it's what kept them alive and kicking butts!
P.S. I also believe that they have big plans for Sinar... and since Sinar is expected to soon enter the "mini view camera" market that is aimed to use mirrorless cameras instead of a digital back, I believe that this camera is designed to perform this task as a major target behind the design... a parameter that has being highly (and constantly) ignored by the participants in this discussion.
