Yeh you'll be seeing PCI Express turning up on the market fairly soon, As for DDR2 expect a slightly longer wait as AMD are not moving to it just yet. Basically DDR2 Offers high bandwidth, but at crappy timings. For the moment AMD are going to stick with Low Lat High end DDR500 - 600 moduals. But when the time comes it will very easy for AMD to upgrade due to the On-Chip Memory controller, so they can do it without the need for new northbridge chips.
