Refreshed iMacs are en route to the United States for a late April or early May launch, reports “9to5 Mac” (http://macte.ch/mnAZR), quoting a source they call “Mr. X.”

Mr. X says to expect new iMacs the week of May 2nd as Apple will officially stop shipping iMacs to resellers this week. Since Apple tends to release new products on Tuesdays and Wednesdays, the likelihood of new iMacs with Thunderbolt I/O and Intel’s latest Sandy Bridge processors is high for May 3 or 4, says “9to5Mac.”
