I didn’t find a way to search this forum so I will go ahead and post this here.
MLG is excited to pick up Halo 4 and is getting community members together like Chris Puckett and some old pros to test game settings.
They have a new show on mlg website (Also twitch and owned when broadcasting) called HALO REFINERY. Its fun and exciting to see the gametypes tested in front of our eyes in Halo 4 because of the amount of options available to us.
Here is a link to the page with all the videos SO FAR

You can follow people on twitter to learn when its live, but keep checking the VOD page for more updates if not.
In case you are totally out of the loop, they are doing things like testing different loadouts and abilities depending on the map/game mode. Some have one frag, some a dmr, some two rifles.
Cool thing about MLG this time around is that it will be almost impossible for them to strip the game down, even if they limit what you can use because of the sheer volume of awesome and viable custom options in Halo 4.
