It appears that Sony's new Blu-ray player isn't the only one being delayed. According to a report at ElectronicHouse.com, the Pioneer BDP-HD1 has also been pushed back to December due to quality control issues.
The BDP-HD1, originally expected to ship in October, will now be available in December. The player has not passed the company's quality control requirements, and it will be available when it does.

"All of the player's specifications had not been finalized in time to meet Pioneer's quality control requirements," the Pioneer spokesperson writes in an email to ElectronicHouse.com.

"The BDP-HD1 needs to pass our testing to ensure it fulfills the high performance expectations associated with Pioneer Elite."
This is actually the second delay for the BDP-HD1. Pioneer originally intended to ship it back in May. If you'd like to read more, the entire article can be found here.
