Personally, I have never had a problem with a console manufacturer releasing updated versions of their product if the upgrades fix a real or imagined problem with the system; the size of the DS (for example) was a huge issue for people that wanted their portable system to be portable and the DS Lite solved (or at least reduced) this problem.
The XBox 360 Elite and 80GB PS3 do not seem to do anything which corrects any major flaw in the systems, and these systems seem to prevent the console companies from addressing the issue that prevents their systems from selling well (the price).
