You can ask the LBS if they can get you the 2010 in the color that you want, they very well may have resources you don't know about, so it's not silly to ask. I know my LBS here has 2010 stock, but I don't think they can order, so once gone-- it's gone.

As to the upgrade to disc brakes, from seeing pics of places you'd like to ride, perhaps disc brakes wouldn't be a bad idea-- just depends on the price and where your budget is. Does Specialized offer a version with disc installed? On a higher model? If your really sold on the better brakes you would have to price it out and make the call there. Could you ask others mnt bike riders in your area about disc brakes? Are they truly needed??

Good luck!!!
