Those two "divisions" - Walt Disney Pictures and Disney.com - are 2 separate entities with their own company setup and business strategy and do not necessarily connect to each other. The movie is bigger in cost and revenue, I think, and with the nature of a movie enterprise, they already knew the exact schedule when to release the movie (to kick off summer here in my part of country). The Potco division at Disney.com is probably not a big; I even doubt they already knew if they could make it to finish an addition to the game such as Queen Anne's Revenge by the movie release time, much less to add a new system. Maybe I'm being sarcastic here.
I'm not so sure about the Tweeter and Facebook thing connected to the weapon award. It sounds rather complicated to connect an Account ID with Facebook/Tweeter to recognize/track who is entitled to receive a free weapon (then we would have to sign up on Disney Potco FB using our Acct ID, maybe?).
But for the Outfit of the Month, I so agree ... Disney Potco already had that planned way ahead of time. They should know that the movie was done and waiting to be released on May. So they could've used it as an opportunity to get more customers on Potco and used it on Potco big advertisement - like what we discussed on the other thread.

Maybe it would say, "Get Your Very Own Favorite Potco Character Outfit on May - Don't Miss It!" - or something like that.
