Only thing I saw on the new Inferno that I could potentially have problems with was that they removed the arch things moving up banana that have been there since Source.
As open as they are they did provide good cover in the appropriate situation, now that there's nothing there and the fact that it generally seems more wide I feel like you HAVE to fully commit to taking banana, you can't stop halfway.
I didn't play much of 1.6 at all, but I recollect Inferno's banana being similar to this new one, but I would've thought that was more just due to a limitation of some sort (map creating tools etc).
(Banana in 1.6)
Little changes like these keep the map interesting, yeah, but I don't know if they are always for the best. I'm all for the other obvious changes though, like making pit more open and having A bombsite have no roof, hopefully leads to some sick 'cross map nades and smokes.
With all that said though, I'm just a retard who only plays matchmaking; don't take my opinion too seriously.
edit: better pictures, apparently there's an invis wall near apartments, so not as much freedom for across map nades as I thought :(
