On Monday, March 14th there will be a free Todd McFarlane Halo 3 theme and gamer pictures available on Xbox Live Marketplace.  I checked out the theme and gamer pictures and they are pretty good looking.  I'm definitely going to download both and change my theme.  I'll also update my external gamer pic as well.  This is just in time with the new Halo 3 maps coming out on Tuesday.  I'll be downloading those as well and I'll give you all a review of them but since a new Lockout is included I definitely think these maps are a solid purchase.
