This list comes from the Mountain Lion installer. We added on the side the name of the oldest model supported for each line of product. The Mac mini and Xserve are the two lines that appear to pay the highest price, for the Mac mini the models that came out before 2009 will not be supported and for the Xserve only the Xeon Nehalem will be supported. It is interesting to note that the 2008 Xserve is not supported while the Mac Pro, which has almost the same architecture as it came out that same year is supported.
For the laptops, all the non-unibody models are left behind. To make the long story short, any model that doesn't have an NVidia 9400M or and Core iX for the laptops, 64 bits EFI for the Mac Pro or an aluminum frame will be left behind.
Of course, this list will be completed with all the products that will come out before the release of Mountain Lion.
