The August 1 sell out deadline was premature.
Sony is not going to make new 60 gb models but they are going to have those models around for a while still because there are a lot around.
Here is SCEA basically saying this:

By the time those sell out the 80 gb will probably not be special edition anymore and will be come the new sku.
Thanks to Blacksaber for the sig!
