Just a quick update with regards to the above post.
The funding has now been approved, so everything is definitely going ahead. I can't be arsed to cut and paste various news articles that people aren't bothered about, but here's a quick recap for anyone that's interested.
Since the Hong Kong Government own more than half of the park, then they have to pay around HK$5.5 Billion (£545 Million / US$706 Million) towards the cost of the project, which obviously some people weren't happy with since it's essentially taxpayers' money. It's been going back and forth at LEGCO (HK Parliament) for a few weeks - "the money could be spent on public housing, social inequality, education, health, the environment yadda yadda yadda" - but that's not much of an argument when Hong Kong is sitting on HK$860 Billion (£85 Billion / US$110 Billion) in cash reserves which aren't being used to fix any of those problems.
Anyway, they recognised that the park has to expand to stay relevant and the spending has now been approved, so everything should be on track.
Also, I have it on (relatively) good authority that between the Frozen land opening in 2020, and the Marvel attraction in 2023, something else will be getting a retheme. Total word-of-mouth, pinch-of-salt thing rather than concrete news obviously. I have no idea what, realistically, it could be if it is true. Tarzan's Treehouse maybe? That's always seemed a bit crap. A permanent Space Mountain retheme to something Marvel-based since literally everything else in Tomorrowland will be Marvel? The only other thing I think it could be would be a new show in the Lion King theatre since it's been there since the park opened, but it's still massively popular and, unlike the old Golden Mickeys show which was replaced with Wondrous Book, isn't in the slightest bit outdated.
