@VanillaLake: Indeed, sometimes backing the underdog has its' benefits. MS need to do some serious catching up sales wise so they are pulling out all the stops which is great for us gamers.
Personally I'm really looking forward to the expanded BC catalogue going live, it means I can just have the one Xbox console and (hopefully) access ALL my favourite games, regardless of generation, on it. It really is living up to its' 'ONE' name for me now. The Elite controller rocks too ;-)
