The war for the all mighty Holiday dollars has started in the camera department. Nikon launched a spirited attack last week with news of it's brand new D40 with a street price of $599.95 for body and lens Canon doesn't have a new camera to launch but that doesn't mean they're staying out of the game this holiday season. Instead they're dropping the price of their immensely popular digital Rebel XTi to $599.95 for the body or $699.95 for the body and lens kit. It's going to be a very merry Christmas for camera shoppers.
