There is no way that they would ever change course of the design this late in the project. This has been in the works for 2 years at this point. The colour scheme was decided on long ago, visualisations would’ve been made, the tracks already been painted, it won’t be changing.
I’m sorry but why is this even being speculated on? The response to the track has been broadly positive, it’s not like it’s sparked revulsion in the community and even if it did it really wouldn’t matter. Times when enthusiasts have managed to make change happen (Like the Oblivion sponsorship in 2011) are the exception and not the rule and certainly wouldn’t be happening on projects of this scale. This is a project with millions of pounds invested into it, they’re going to be confident with their decisions whether we like it or not.
