Its supposedly using material done a good ways back, like early 90's I recall, with Wright.
That makes me skeptical. If teh material were anything special, we'd probably have seen it a long time ago already.
But you never know. We'll see.
I'm hoping they do something to attempt to make this material more in step with the times. New Pink FLoyd material in 2014 would be a curiosity at a minimum.
You know, something like Porcupine Tree, Muse, and Radiohead all rolled into one. Oh and with both Waters and Gilmour.
Toss in some Dream Theater, Mars Volta, and Broken Social Scene for good luck.
