I'm considering buying a PS3 and have a question about the new 80GB model. Given that the 40GB model is to be discontinued I'm expecting that there will be a few on clearance allowing me to save about $100. So the big question is, Other than the 80GB HD, is there any difference between the old and the new PS3. I've read on the Internet that someone has measured a 10watt reduction in power consumption which they speculate is due to them using a finer process to build their CPU/GPU. But other than that, are there any published differences that anybody's aware of? Also one point I found out is that there is an 80GB version which was available in the US for some time, which has all the features of the 60GB model here.
