You all MUST of heard the rumour of moving the park entrance to somewhere round FV/GW though? & if they did that, there'd be no need for the monorail, you could access the park direct from the car parks! The skyway would then become a transport hub, one way for DF, the other way CBB/XS.& with some guests on foot splitting between FV & KC, there will be a more even spread of guests accross the park from the new entrance plaza.
This also leaves all of the current entrance plaza & towers street empty (other than shops). That's right next to CBeebies, which is already rumoured to be expanding.
My money's on the dismantling of the Monorail & Duel & the new entrance plaza between GW/FV as has been already suggested for 2016. CBeebies being expanded the same year (Possibly with the next SW, although I hope not!) & some reworking of the ride system from duel into a NEW haunted house put over in GW the year after, maybe on the site of the current burger restaurant (Ironically, the site of the original haunted house, Doom & Sons!)
No evidence, just speculation. With a good deal of logic & rumours backing it up!
