Before the 802.11n draft was ratified, Apple had quietly been introducing the "draft n" hardware for a few years, enabling the functionality later through a driver update (source). Let's hope they have had the foresight to do the same this time around. Hopefully the teardown will reveal wi-fi hardware choices.

Judging by the pic of the new MBP internals on Apple's site, it does look like the wireless components are on a removable daughter-board, so there may well be the possibility of an upgrade (3rd party or otherwise) in future.

Good evening, now that the teardown is over, I was wondering if you have any more information about a possible upgrade with a 802.11ac chip ?

Thank you.
