Verizon just put out this press release explaining the Nexus delay.
"Basking Ridge, NJ
Verizon Wireless, a leader in global telecommunications is pleased to announce another first in it's history. Today we would like to announce the first irrefutable evidence of an afterlife. For the past month, our headquarters have been haunted by the ghost of Steve Jobs. We have tried unsuccessfully to launch our new flagship device, the Galaxy Nexus, on the nation's best 4G LTE network, beginning with a planned release in early November. Shortly after internal communications were leaked to the internet, strange and paranormal activity began at our headquarters, with files, documents, and merchandise going missing or being edited without anyone's consent. Shortly after these occurrences began, a strange man was often seen wandering the halls muttering the phrase "this changes everything", and "I will destroy Android, " along with disparaging comments to staff members . Investigators were utilized and it has been determined that this poltergeist is non other than Steve Jobs. We are honored that Mr. Jobs, a visionary and genius would team with Verizon Wireless to introduce the next big thing. As of now we are still planning to introduce the Galaxy Nexus in 2011 as long as the exorcism is successful."
I have also confirmed this with a source.
