I mean he did since he referred to low quality POV stills...I suppose you did not see the testing footage in the bottom right? Does not per se make it more relevant as we know that it is testing and it's just a image
Image is from after it passes over the 1st launch after the Zero-G roll with the building being the one that houses the pre-lift.
An April opening is not happening; after all as recently posting they are offering discounted tickets for that month. Would make sense to lure people in before opening a new big attraction. Plus with the progress being made and testing underway a May or June opening seems feasible, and Phantasialand typically opens most attractions during this period just before the peak summer time.
It will be interesting how they announce and handle it though. A 2 week in advance Klugheim style announcement seems unlikely - they'll want people to prebook rooms for the hotel. Also typically hotels (certainly Ling Bao, Matamba and EP's Kronsar last year did) have a pre-opening test phase. For reference Matamba opened 23rd August 2008. With a pre-opening phase from 14th August. The opening date was announced and bookings started to be taken on 19th June 2008.
