So what does have to do with the release of the 5 instead of a 4S?
Sigh...
Like I said, There's proof around that Apple was working on iPhone 5 alongside iPhone 4S. When they couldn't finish the 5, instead of releasing it after Steve's passing and getting it buried in news of his death, they opted to release a more complete and finished but lesser iPhone 4S before he went to avoid such a disaster.
