According to this post on Roger Waters Facebook page Pink Floyd reunites.
The full post reads:
"Pink Floyd reunites to stand with the Women of the Gaza Freedom Flotilla"
David Gilmour, Nick Mason and Roger Waters stand united in support of the Women of the Gaza Freedom Flotilla, and deplore their illegal arrest and detention in international waters by the Israeli Defense Force."
So no. No shows, no album, but a joint statement is what this is.
