I've said for a while now that it may or may not happen but if it doesn't it's not because the whole thing was some kind of charade; it'll be because the numbers don't add up now compared to when the original plan was mooted or because there will be an insurmountable issue with the planning permission. There have been a few vociferous doubters on other forums who insist the whole thing was a scam for want of a better word yet have yet to come up with what that scam would be.
I'm more confident now than at any time about it, but I doubt it's a done deal yet.
