Don't get me wrong, the heights sound exciting. But these are proposals. The Transbay Towers are proposals. The TransAmerica Pyramid was proposed at 1150', only to be reduced to 850'. Many other buildings were proposed in this city, and never made it off the drawing board. I'm not trying to kill excitement, just trying to remind people that things like this 1) take years and years to propose and flesh out, not to mention years more to build, and also that 2) these proposals meet a great deal of resistance in San Francisco.
