We're going to have a beta war sometime between launch and Christmas where we'll try to test stuff like gametype settings and get feedback on what people like about Halo 5. It'll probably start off with default 4v4 maps but if BTB is added quickly enough (which I think it will be) we should be able to try a few of them out as well. Forge will be released somewhere around the time that we take a break for the holidays, so we'll have it available to make map adjustments for the first official war, which should start sometime in January.
