Crunchgear claims that there will be a "substantial" update to iTunes this month to provide High Definition content. Accordingly, Apple has reportedly placed a large order for Apple TV's in anticipation.
CrunchGear has not been an accurate source of Apple rumors. Surrounding the previous iPod Nano rumors, they claimed that the Nano would come in 8GB and 16GB versions and not be called "Nano" any longer.
The site had also claimed that Multi-touch MacBooks would be arriving this month.
