Prior to it being announced, I can't say. It's clear they had the placement of New Orleans Square in mind for it when they came up with the idea. But the initial concept art they released was based on the version at WDW. So around the time it was greenlit, they did intend it for both parks. And again, it was still in very early stages at the time without a settled on concept.
I believe Tony still routinely visits WDI to observe, socialize and give advice (even if his opinions are often disregarded). He's very well connected and can find out anything if he wants. Especially this project. Unless he has deliberately refused information offered to him about it, I cannot imagine that he would be in the dark about what they're doing with it. Not to mention the prevalent rumor (something my source now seems to lend credence to) is that he left the project due to not liking the plan. That would suggest that he has some degree of knowledge of it.
He again almost certainly has some sort of NDA that would prevent him from sharing obvious details or opinions on current WDI projects. His comments about Tiana itself were vague. But at the same time, he focused on interesting details when discussing what made Splash work so well. Details that we coincidentally know Tiana contradicts. He disparaged overdone storylines that treat guests as if they're stupid. He went into detail about how the big drop was enhanced by the dark and scary nature of the final lift. And how the finale scene was designed to be this huge celebration with tons of animatronic figures that was your big reward for conquering the drop.
It's interesting because these are the inversely connected to many of the more pronounced complaints we've had with Tiana. The ridiculously preachy and over the top mess of a backstory. The final lift is being changed to be bright and cheery. And if SplashArchive's claims are to be believed (they've again yet to post the renders they said they possessed), the finale is being dumbed down to only 6 or so animatronics and will heavily feature video projection instead of physical setpieces.
I'm sure Tony knows full well most if not all of the plan they went with. But that was the most he can say legally to the public.
