I have a 2009 octo mac pro and I really, really need a single-height card with 3 or 4 mini displayport outputs on it. Currently there is NO three-port option of any kind available in single height - you have to go dual height and one of the ports is DL-DVI. These cards (eyefinity, etc.) have been out for a LONG time now - do we have any guesses as to when the extremely anemic, getting older every day, very sparse-port-options cards will be refreshed ? How often do they do this ?
