Need a replacement for my aging original 2008 unibody 15" MacBook Pro. The refreshed design 15" MacBook Pro looks great, but still hoping for a 15" with the Air Profile. Although the Retina display is nice, it is not on my must haves. Prefer something that is thin, light, but still 15". What are the chances a 15" MacBook Air will be released within the next year? Oops just realized the title says Pro and not Air, sorry.
