Halo 2 Expansion Pack?

Here is an article about a sort of expansion pack for Halo 2. For those of us who prefer not to pay those outrageous fees of 50 bucks a year, Bungie has decided to release this with a whopping 9 new maps. A few are remakes of the old Halo levels, but with new age technology, while a few are entirely brand new. Although Hang 'Em High isn't in the forecast, it only has a few screenshots, which means there is still hope.
