I just saw this posted on CultofMac a few seconds ago. It says Apple is hinting that an iPhone 5 will be coming out simultaneously this summer.

After reading the quote "But if it does, and you buy an iPhone 4 now, youll be stuck with an outdated phone in only five months," I get the idea that this is showing no new iPhone 5 because who wants to be "stuck with an outdated phone in only five months." Maybe someone can clarify this but it seems to me this is backing up the OP's claim.
Also, why hasn't MacDawg come back and said whether or not his "proof" is legitimate and why hasn't the OP responded to his "I work in an Apple store, I'm all knowing" comment as well.
