** The following is rumors only and not based on facts **
If this rumored 80GB PS3 is real Sony most likely will discontinue SKU number 98000 (60GB version) after stores start getting low on inventory.
The rumored 80GB PS3 is suppose to have a SKU number of 98004. Here is a link with possible other changes. Also the PS one and PS2 hardware emulation chip is being removed according to rumors. Software emulation will be used to keep prices low. If these rumors are true then most likely the 98000 PS3 will be out of production soon and in October the 80GB PS3 with more integrated circuits and less components will be selling for $499.
