From DisneyParks blog,
Over on Pleasure Island, we’ve completed removing some of the buildings that aren’t part of our future plans. During the course of this site work, we identified opportunities to further refine our master plan and are pausing to evaluate them. What does this mean for you? While we’re moving quickly, it will admittedly cause a delay in construction. But we’re willing to bet that any delay will be worth the wait once we’re able to share details about the exciting work we’ve been doing.
