I am still getting conflicting information on the Leica S3 sensor - some old reports indicated a completely new sensor inside the upcoming medium format camera, but the latest rumors point to a sensor with the same MP count and this time with live view (Leica S2 has a 37.5MP CCD sensor without live view). The other expected upgrades in the S3 are build-in GPS module and a new menu system.
There will be also some new Leica S lenses announced at Photokina. Some of them were already included in the latest Adobe Camera Raw 7.2 release candidate:
- LeicaLEICA VARIO-ELMAR-S 30-90 mm f/3.5-5.6 ASPH
- LeicaLEICA SUPER-ELMAR-S 24 mm f/3.5 ASPH
