Apple has updated its online store iMac page to note that new 27-inch iMac orders will ship in 3-4 weeks after ordering. This timeframe likely puts new deliveries into early-to-mid February depending on shipping options. Apple no longer says that 27-inch iMacs will ship in January, making it all the more likely that new orders will land in February at the earliest. The 21.5-inch models continue to ship in 7-10 business days.
