Last week an analyst report speculated that Apple would hold some sort of media event this September to refresh the iPod line as well as long awaited updates to both the MacBook and MacBook Pro lines.

While the report appeared to be mostly speculative, Apple has been predictably updating their iPods in September for the past couple of years. Combined with circulating rumors of iPod revisions and the end of the Back to School promo, it seems probable that late September will bring us new Apple products.

While rumors have primarily focused on new iPod nanos, we've heard whispers that an iPod Touch update is also likely in the same timeframe.

Given the likelihood of updates, readers should be cautious about buying a new Apple notebook or iPod at this time.
