I missed the discussion. Sorry.
I find the possibility of any of Toontown remaining bad news. It just doesn't fit the backstory of Fantasyland Forest. I think the author may be reading too much into what the Imagineer said. I can't imagine they are considering keeping the M&M houses. The only place I could see them is behind the Goofy's building on the small path to TL. Perhaps designed as a mini cartoon version of MSUSA. But there definitely is not room for M&M M&G's. I think it would be a terrible mistake to scrap PH for a toontown featuring the fab five. A fully realized toontown is a much better fit for DHS. The houses will not be staying in MK. They are going somewhere,but I have no idea where. DHS is my best guess.
I also found it very interesting they haven't decided on a theme for the barnstormer. I wonder if Alice or a SW runaway mine are still on the table? That would make no sense. its too close to the Dumbo area.
Finally, I'm encouraged they are putting a lot of thought into landscaping design even to the point of rendering a virtual FLE to verify sightlines etc. This is the most important aspect of the expansion IMO. That and how to handle all those strollers when the millions show up. Because they will because this is a brilliant concept. Yes. They are certaintly putting in an extreme amount of effort. Good sign.
