No design lasts forever, regardless how iconic its status. Surprisingly, disregarding some internal changes, it's been almost eight years since the current aluminium case of the Mac Pro (previously the G5 PowerMac) was released in mid-2003 with the G5 1.6, 1.8 and 2.0 models. I remember opening up our new work G5s at the time and being amazed at the ease of access and the elegance of its internals compared to my dual G4 which was comparatively cluttered. Before then, the overall form (excluding changes of colour and materials) of the G4 PowerMac lasted from 1999 with the Blue & White Power Mac G3 until 2003, when the dual G4 1.4 was released... only four years. So, it's my guess that within the next 2-3 years we'll see a new design, possibly sooner, assuming that Apple still continue with a professional model and that it's a tower of some form or another. What would you like to see; size, form, materials, finish-wise? And what improvements do you think could be made on the internals to fit within it and to accommodate new technologies?
