That means you're asking for a camera body with a prism hump twice as big as it currently is.
The A900 could have saved at least four or five millimeters of prism housing height by just replacing the expensive (in terms of space and money) condensor lens with a cheap Fresnell lens, as virtually all SLR cameras since the mid-'60s do. I am glad Sony, in a truely Minoltian twist of mind, opted for the deluxe version of an SLR viewfinder (much like Nikon D3 and D3X), even though most customers will neither notice nor appreciate---instead those fools badmouth the prism housing's "ugly shape".
With the Dynax 7D I have learned to appreciate a built-in flash. Still I gladly give it up for a better viewfinder. So from a sales manager's point of view, Sony possibly may have made a mistake. From a photographer's point of view, the decision definitely was perfectly right. And after all, I have seen two A900 bodies in the hands of---most likely ambitious ---amateurs (besides mine) in the wild but no Canon EOS 1Ds Mk III and no Nikon D3X yet.
