My realistic lineup prevision:
11": i5 1.4 GHZ, 4GB RAM, 64GB SSD, HD3000, 768p, 999
11": i7 1.5 GHZ, 4GB RAM, 128 GB SSD, HD3000, 768p, 1199
13": i7 1.5 GHZ, 4GB RAM, 128GB SSD, HD3000, 900p, 1399
13": i7 1.6 GHZ, 4GB RAM, 256GB SSD, HD3000, 900p, 1599
15": i7 2.1 GHZ, 4GB RAM, 256GB SSD, HD3000, 1050p, 1799
15": i7 2.3 GHZ, 4GB RAM, 256GB SSD, HD3000, 1050p, 1999
/$ stays pretty much the same. 17W on 11"/13" for 6/10hrs battery life, 25W on 15", still 10hrs (12?) because of bigger battery allowing also 2 ram slots maxing out at 8gb on BTO and 512gb for more flash memory modules. Also, getting the base 15" air at the same price of the 15" pro with stock SSD and higher res screen must be important for apple, as they still make higher profit margins from Air.
