So, is he saying that for the next few years the MBP will not support 32GB of RAM? It's not that battery technology is moving forward that fast, and I don't see apple making a thicker laptop.
No, he's saying that we'll be able to have 32GB of RAM on a MacBook Pro when they'll be able to get an Intel processor that supports more than 16GB of LowPower RAM, which means we'll get 32GB of RAM on our laptops when Intel wakes the hell up and starts delivering on their roadmap.
