Sony is introducing a 50mm OIS f/1.8 and it is larger than the Zeiss. There is one set of samples floating around and it looks like a very capable lens. That would make two or the bunch.
The Zeiss lens is large because it is a fast lens which covers a large sensor area. Can a smaller, less capable lens be made? Sure, but I think that the Zeiss lens was a counter to all the poor quality lenses presently available for the NEX system, which was initially marketed as a cheap APS-C system. Price was certainly the objective with their present lens lineup. We have yet to see if the Zeiss delivers.
You need to use a smaller sensor camera, non-autofocus lens, slower lens, or optically inferior lens in order to shrink a lens. You can't do it with magic, or wishful thinking.
FWIW, I believe the NEX 50mm is actually a tiny bit smaller than the new Zeiss 24.
