Apple's typical playbook: offer new high end product in new product category at high price point, reap sales, eventually introduce lower spec product at lower price point, reap sales. Might they have decided to do the MBP the other way around? Realizing that it's an established product with a loyal following, why not offer a lower spec'd (compared to what they could build) but high profit model, get the sales, then offer a "dev edition" at a higher price point down the road?
