I know this isn't FFXI, but this is also ARR's first true expansion, so there's no precedent; FFXI's PlayOnline launcher only downloaded the content necessary in the event expansion gear walked back into standard areas, but did not download the full content even if you had it registered. You still had to run the install disc. Granted, this was in a considerably less digital age, so that may mean nothing, and the content "lock" will (hopefully) come down to only which platform/expansion licenses you have.
