I think it's quite clear that as things stand, this ride isn't delayed... I'm just worried that with such a large gap in their marketing, apart from the release of their overpriced Photography Box, it's a bit easy to loose interest in the project.
It dosen't help, I don't think, that the last we really heard of the ride was of a video that really underwhelmed many people who saw, and I would have thought more marketing since then to try and appeal to anyone who might have been put off by the testing video, would have been a good strategy to have.
I think we have to consider that the testing video was shot at presumably at a very early stage of testing. We don't know when Wicker Man started officially testing but I expect that run was very early. It was in cold winter weather, the wheels were new, the track's new. there are a lot of factors that can slow a ride down in testing especially in winter.
In John Wardley's autobiography he speaks of Vampire’s first ever (secret) test run going slow and stalling because of inadequate weighting but also because it was the first test run. He states: "once a rollercoaster is fully run-in it is perfectly capable of getting round the track empty and without passengers. But for the first run in cold weather, when everything is new and the wheel-bearings are stiff, extra weight is needed to give the train added momentum."
Do take that video with a pinch of salt.
