August Rush score album?

Has anybody heard if they will release a score album of Mark Mancina's "August Rush?" I bought the soundtrack album but there was pretty incredible music in the film that didn't make the album and I would love to find a score album of it. Have there been any composer promos floating around ebay?

email me if you have any information

thanks
Matt
