Apple has not announced any type of upgrade path except for mentioning that new MacBook Pros will be available with 802.11ac at a later date.
More info may be available at a later date, but I doubt that Apple will offer an official upgrade option for previous versions of the MBP....my opinion.

The ac module is called QCard 2. What do you guys think about it? I just asked a compatibility question on QuickerTek, Inc.'s facebook page.
