It sounds like a bit of a departure from his Culture and far-future sci-fi, as this one is set on Earth in the (near?) future. It sounds like it may be more like some of Ken Macleod's books (or dare I say it, "The Diamond Age"). There's not really enough info on Amazon's page to know, though. So I guess I should be patient :)
It's available now for pre-order from Amazon (hardcover)... The softcover version will be out later in the year.
There is also an interesting article featuring Banks and other sci-fi authors on the BBC website here. The topic is "Can science fiction keep up with modern science?"
