Hi there, Steven!
The 2012 Vacation Planning DVD is, according to the Cast Member with whom, looking at a later reveal. This is due in part to the huge Fantasyland expansion in the Magic Kingdom, footage of which will likely be included on the 2012 DVD. Right now, as the expansion is still in construction phase, the shots for the DVD wouldn't be ideal.
There is also some speculation that since the "Let the Memories Begin" theme is remaining the same for 2012, a new DVD will not be released, and the next reiteration will occur in 2013, when the Fantasyland expansion is well on its way to completion and e theme change might be in the works.
For a fun and maybe more current look at the Parks, visit the
Disney Vacation Planning DVD page, and click on the "Watch Now" link by any of your desired categories.
Happy planning!
See you later, celebrator,
