Yes it would be odd that they announced it so far in advance but then again ... do the majority of the parks visitors know or care about F.L.Y. yet? And regardless of that maybe Phantasialand are fairly confident that it won't affect their numbers next year. Taron will still be the main focus of their marketing. It has been a massive success for the park and could easy sustain them for another season as the big new draw for visitors.
Someone above made a remark that Klugheim flew up quickly so Rookburgh might do the same. This time last year half of Klugheim was standing and Taron's track was completed in October 2015. Rookburgh is still just concrete foundations in the bottom of a big hole with a small corner filled with some buildings and track. As the park would like to reveal things in their own time and keep things secret photographs are not allowed to be publicly shared and to respect their wishes I'm not posting any here.
With regards to the announcement:
Taron was announced April 2015 and opened June 2016. So just a little over a year in advance.
F.L.Y. was officially announced June 2017. I would imagine if it is 2019 they might get it done for the start of the season so lets say it opens in April 2019. That is still an unusually early announcement. Unprecedented in the park's history (except Chiapas but that wasn't planned for 2014...).
They started installing track for Taron before it was officially announced and rumours ran wild - especially the Screamscape claim that it would have Skyrush trains, dark ride bits and multiple trick track segments - that rumour ended up everywhere. Maybe they wanted to avoid any misconceptions flying around?
My main suggestion for why they announced it so early is:
- With the first supports and track installation not far off (31st July), and then track parts, including the launch parts, being visible at Vekoma Vlodrop; the cat would have soon been out of the bag anyway. We would have known a launched Flying Coaster was coming.
And Looopings had kinda already spoilt the surprise with their leak that a Vekoma Flyer was allegedly coming back in April.
So why not announce it first to surprise people, and create a lot of hype and interest?
Will be interesting to see how construction progresses between now and Christmas. If there aren't any major developments there won't be a chance in hell it will open Summer 2018.
I still think it will be 2019 now. There is just so much to do and PHL like to take their time to create quality stuff.
