There could be a 12 inch Macbook with retina display coming out in mid 2014, according to analyst Ming-Chi Kuo of KGI Securities. According to him, it will have a redesigned clamshell and is thinner and lighter than current MacBook Airs.
It's still a rumor of course, but the prediction matches a report released earlier this week by NFD DisplaySearch that indicated a 12 inch MacBook Air debuting in the same timeframe would have a 2304 x 1440 display.
