Well, according to this piece of information there will be no iPhone 5:

I think we will all be disappointed, hard to believe move by Apple, so many people are unwilling to buy a 4S. I have a 3GS, but that was different because apple was still ahead in the market, with a 4S apple will fall behind, as an apple fan, this is disappointing as Android phones are currently more appealing. However the demand for a redesigned iPhone 5 is high.
It is also hard to believe that apple will be holding an iPhone keynote, apparently a small one at it's campus though, just to introduce a spec bump. My last hope that possibly apple hasn't started assembling the iPhone 5 and will announce but release it later on.
