On top of Monday's rumor that Apple would be announcing a new 13-inch MacBook Pro with Retina Display comes a rumor Tuesday that Apple will refresh its popular Mac Mini computer at the event as well. Apple blog 9to5Mac reported the news, citing sources. Apple will reportedly announce three different models, two with different storage and chips, and a third one that runs Apple's OS X Server. It is expected that the new computers will ship immediately.
