And let's not forget, the Disney Marketing Machine has been getting Tink and da Gurls ready for the new wave. While I doubt the Princesses are going anywhere soon, the Fairies are being aimed at a different segment - older and edgier from what I've seen.
With Pirates, I doubt we're going to see them let up on it much. We've all heard that Pirates 4 is coming down the pipes (sans Orlando - 'bout time for him to die heroically), which means a few more years to milk it. Plus, pirate theming has been part of geek sub-culture for a while (hacking, Pirate vs Ninja, etc), and they can hold onto a trend for a long, long time (Star Trek...I rest my case.).
If Robinsons does well, how long do you think it will be before Tomorrowland is renamed to Todayland (a truly awesome pun if you ask me)? If Jungle Cruise does well in the box office, how long before that classic is overhauled?
Personally, I love Pirate theming and Disney is the first company to make a success of the genre in 50 years. It's fun, and honestly, it's a dive into seediness that Disney doesn't usually make. Here's hoping that Jack continues to be a drunken chum-bucket!!!
