The spoiler button is still there - it's just that it looks different in SMF 2.0 than it did in 1.1:

And it's also possible to make a custom title for the spoiler. For example...
As for the foyer, all the descriptions that we've heard of the sets, from when they were first built to when KLS and Lara Parker talked about seeing them for the first time have said that they're huge so it shouldn't be too surprising that the foyer looks big in the new photo. Though honestly it doesn't look as big as the foyer was in the '91 Series - but that could simply be because we're only seeing a portion of it in the photo. If we'd only gotten a shot of the staircase in the '91 Series' foyer, it wouldn't have looked as big as it was either.
Also, as far as the window goes, people might be on to something about how the window is such a prominent feature of the set. Though as far as the what's on the other side goes, it looks to me like the backdrop only goes up the window about two thirds of the way and what we're seeing at the top could possibly be whatever is actually in the studio on the other side of the set's wall.
