Earlier rumors have suggested that Apple could have run into some production issues with the 5.5-inch model of the iPhone 6. The 4.7-inch iPhone 6 is apparently on track and could be released in the next few months, while the larger iPhone model is said to be delayed possibly until 2015.
This will be an interesting move for Apple as the company typically favors releasing products ahead of the Black Friday sale in November, so a release in December does seem a bit late and could possibly miss the holiday shopping deadline. However it is also possible that Apple could release the 5.5-inch iPhone and iWatch in limited quantities in the meantime to appease customers while they work on churning out more units.
In any case take it with a grain of salt for now, but if you were eyeing either the 5.5-inch iPhone 6 or the iWatch (or even both), you might want to prepare yourselves at the possibility that you might not be able to get your hands on it this year.
