Lust for a design change for rMBP. The design remains unchanged for almost 3 years. the current 13-inch rMBP is good, but only with incremental hardware changes internally. Even if they update the 15-inch model, it would be no big deal. I'm not saying that the design for the current rMBP is obsolete, but it's time for them to redesign and refine the rMBP. I don't want to buy the current rMBP and get in huge disappointment when the next model comes out.
