Tomorrow, Wednesday September 9th Apple is supposed to unveil new iPod players at the It's Only Rock and Roll media event in San Francisco. All rumors point to video cameras integrated into new iPod touch and iPod nano players.
AppleInsider reports now that the launch of the new iPod players with cameras could be delayed due to technical issues with the camera modules.

AppleInsider basis this report on a person with a strong track record in predicting Apple products.
This news does not necessarily mean that Apple will not unveil the new iPods at the event tomorrow, but sales could start later. Usually Apple tries to put newly unveiled products up for sale immediately. If Apple doesn't introduce new iPods what else could they unveil at a music centric event.
