I am personally holding out for the dGPU specifically. I feel that the retina display could benefit from a card other than the 650m, it's not that powerful. Competitors have already made similar thin form factor laptops using the more powerful GTX 765m, with 2GB GDDR5 for a lower resolution screen than the retina display.
Razer is doing it right now, in a 14' with similar specs - Razer Blade
If they can do it, Apple can definitely pull it off. Otherwise I'd rather just go for an air if I had equal or less dGPU performance again.
