I haven't had time to swing by, does the Apple Store stock 16GB rMBP models, or is it something I would have to get online?
Select stores now offer the "ultimate model". 2.7 16gb 768gb
Really? Do you know of any particular stores that have actually received this model? I've called all stores in the MD/VA/DC area, and not a single one has claimed to have in stock (or have even received) the ultimate model.
No, I believe that 16GB RAM is BTO only.
Yes, but don't forget the new MBP doesn't support ram swaps. At least not in a easy manner. So they could be right. Unless the store itself ordered the top model, they may not get it.
