I would advise to read my opinion about 2012 Airs before reading this, not wanting to crosspost but I think this could make a lot more sense after reading the other thread. BTW, Screenshot. My logic for this mock-up: a) Apple has two 35W quad CPUs, one 45W but could kill battery life, virtually no declared 25W quads but a lower-clocked i7q appeared in the OEM list, that could be the one for the 13" Pro (25W). b) Apple kills SuperDrive. Pro line has more free space in chassis. 13" gains discrete GPU. c) SSD for caching. mSATA form factor (like Air). Intel Ivy Bridge Smart Response Technology automatically caches most used data on SSD up to 64GB. Little space used in chassis. d) Standard 8GB RAM for avoiding Macbook cannibalization (read Air mock-up thread). e) GPU: 13" gains lower-power AMD GPU, 15" and 17" more powerful ones (in line with battery size). f) Retina display standard. Again, to avoid cannibalization. g) SuperDrive loss allows for bigger batteries. 8-10-12 hour for wireless productivity. h) nVidia could be too late with the new GPUs for Q2 2012, AMD will be ready before Ivy Bridge. i) Pro becomes more "Pro", price of 13" increases as differences with 15" decrease. Less BTOs and SKUs for mass economy logic. Not saying that Apple will do this (reeeeally slim eventuality), but I would like too see what you think, because IMHO this could be one hell of an upgrade to the MBP lineup!
