Let's be realistic. If they are really going to deliver in September. Then, they should be tweaking some prototype NOW, OR at least show us some photo of their 28nm chips, OR at the very least, some photo of the shinny wafer. But do we see any of those?
What are you talking about? You design a chip. Then you send it off to the fab to fabricate, dice, and package. Then you wait three months, and then you get your chips in the mail.
The only way to get "prototype chips" is to do a small order early, test, and then do another order later on. But that process takes 6 months.
If you do your whole order up front, then there
are no prototype chips, they are never created in the first place. KnC will get it's first chips in September, and those will be sent out to customers.
There is a small chance the chips won't work, but that's unlikely.
If you think they'd have prototype chips at this point you don't understand how ASIC production cycles work.
