AppleInsider sources say that Apple will officially announce and sell the new iMacs as of May 3rd, this Tuesday.
The new iMacs will in all likelihood see a processor refresh, replacing the first generation Core-i processors with the new Sandy Bridge processors. They should also receive Intel’s Thunderbolt, which boasts ultra fast transfer speeds and can even support displays. Both of these updates appeared in Apple’s latest line of Macbook Pros.
A touchscreen iMac is probably a long ways off and as a result you should probably expect the form factor, and size options, along with price, to largely remain the same.
We’ve been hearing about an iMac refresh since March 22nd, with the latest one pointing to an early May release. Apple hasn’t updated their iMacs since July 27, 2010, when they added i-Core processors, so it’s an overhaul that is long overdue.
However, Apple’s online store is still displaying a 24 hour ship time for all iMac models. Historically, Apple will delay the expected shipping time of a product when a new iteration is due within a matter of days. Nonetheless, it stands to reason that they’re no longer displaying this information to the public and instead notifying individual customers by email after an order has been placed.
