Hi all. I realise the new MBP Retina was only released Monday, and its probably still too early, but what accessories would be ok for this ? Based on the fact the Retina is a few inches thicker than the Air, would the a Incase be available for the 15' ? as the current 2011 sleeve i have would be be ok, but there'd be too much space either side. Anything coming in this area ?
