I thought I was going to go the new iMac route when I'll have enough $ in Feb/Mar, but now I'm leaning towards a 15" MBP. You guys would know way more than I about how Apple updates it's products every year, so what do you think? Will the new MBP in June 2013 come with the 680mx currently in the new 27" iMac? Should I wait until June to get one? Many thanks!
