I wouldn't get your hopes up at all for a new Floyd album... it just won't happen... Gilmour doesn't want anything to do with it anymore
if they reunite it would probably be another one-off for something really important... like a huge official Syd tribute/benefit/celebration concert... but as far as touring, once again, it just isn't going to happen, Gilmour has been really open as to why and such over the years
as much as I'd like to see the Floyd, I much rather might just like to see just David Gilmour on tour, because that's where he's happiest and most comfortable in his life right now, and I loved "On An Island"
