From what I'm aware, Thorpe have actually been suffering pretty badly on the guest numbers for a long time, essentially still so since 2012 time, Thorpe's numbers haven't been great and though in 2013 & 2014 they went up, they were still not to the levels of the pre 2011 days where despite the horrid mess of Storm Surge appearing, was around when the park was in it's peak [in many ways].
Apparently Thorpe's numbers were down quite badly this year before Smiler even happened. Part of me thinks Thorpe will be hit just as badly as Towers, if not a little more as a result.
Legoland is the only park doing very well right now [though Chessington isn't doing bad [at least visitor wise], but I wouldn't be surprised to see cuts implemented there too.
Unless Derren Brown is an overwhelming success, I fear 2016 could be a disapointing year and one that will take use back to the epitome DIC 2004 days.
