This is interesting, according to AppleInsider Apple will release new iMac models next Tuesday, May 3. Citing “people familiar with the matter” who have “continually provided accurate information,” AppleInsider states that the next iMacs will sport second-generation Intel Core i5/i7 chips and a Thunderbolt port. It could not be confirmed at this time if the new iMacs will feature changes to the display sizes.
AI also states that its sources said the early morning hours of May 3 at Apple Retail stores will be a “visual night” which means that the new iMacs should be on sale the day they are announced. “Visual night” is the term when Apple retail employees stay through the night and change merchandising and display planograms in the store in order to prepare a new product for sale. In this case, the older iMacs will be removed and replaced by the newly announced models.
