I have to agree with CK. Weren't most of the rumored release dates just that....rumors? Mind you July 28th/Aug 4th aren't solid facts either. Verizon didn't make any official announcements for the Bionic outside of the recent splash page as far as I remember.
Waiting for a device we heard about is not the same as Verizon making us wait for it.
