The problem with equaling the Contax G system is that the lenses were made specifically for the camera body. We need digital bodies made specifically for either Contax G lenses and new Zeiss lenses, or just new Zeiss lenses (probably more viable). Zeiss can do it... but the R&D would probably need to be a partnership since as we know Zeiss will be like "er well if you do it our way the lens will not be too big, but if we have to adapt to your way then the lens will be 85% what it could be and as big as a can of soup." I am fine with large lenses actually... Compared to a 5DII with a 24-70mm 2.8 IS lens... anything will be small.
