Battery readings from a "MacBookPro10,2": http://burgos.emeraldion.it/mbl/list/MacBookPro10,2 Supply chain indications for screens that would fit (2560x1600), for production in the third quarter of 2012: http://www.displaysearchblog.com/2012/06/supply-chain-indications-for-the-new-macbook-pro/ KGI Securities analyst Ming-Chi Kuo's report, predicting a retina MacBook Pro 13" to be released in August (later adjusted to October). S/he was quite right about the retina 15" and the other updates at the WWDC: http://www.macrumors.com/2012/06/08/apple-to-introduce-third-macbook-line-with-retina-display-at-wwdc/ Rumored October-Release http://www.macrumors.com/2012/07/10/apples-13-inch-retina-macbook-pro-to-launch-before-october/ GeekBench results from a "MacBookPro10,2": http://www.macrumors.com/2012/07/10/13-inch-retina-macbook-pro-shows-up-in-benchmarks/ *gathered by Imladris The 13inch Retina is basically a revealed secret, it seems like Apple has been delaying the 13inch Retina Version with the purpose of getting higher sales with the 15inch version. The rMBP 13inch is rumored to have a 2560x1600 Panel which leads to the conclusion that 1280x800 seems to be the "best for Retina" scaling... mathematically this would mean that 1600x1000 is the "more space" option... so you can get the best of both worlds... image quality and if you need it -> Displayspace. Even if it does not have a dedicated GPU, there should be no problem attaching one trough the Thunderbolt-Ports. If Apple manages to create a 13inch with 5Megapixel Screen, Thunderbolt, Displayport, USB 3.0 and HDMI... they basically have the best 15- and 13inch laptops on the market. It is speculated to be released September/early October. ...but whats regarding the price? I think the base version will be listed for about 1500$.
