Remember when the CEO said they don't announce new attractions until the vacation planning cycle for the time period when the attraction opens starts. Which is about 8 months prior to when the attraction opens. So since no major attractions were removed for this, I expect them to hold to that strategy.
I think they will have to address it in their new year blog post but I wouldn't expect anything more than 'we're building a coaster in Jurassic Park'.
No stats, no concept art, no details, no opening date.
