The update you Halo fans have been expecting is due to arrive on the 23rd of this month, says Luke over at Bungie. Luke would also like you to know that any and all mishaps will be monitored closely and they should resolve themselves within the first four to five hours of going live.

When TU2 goes live next week we fully expect a crazy period in Matchmaking. See, there will be a period after TU2 goes live where not everyone will have the Title Update for a number of weird reasons like: You left your box on and the TU came out so folks who turn their boxes on are getting the new patch and you’re playing the previous version of the game; Your Xbox doesn’t recognize a new patch (clear your boxes’ cache – Go to the System blade and select Memory. Press Y on the HD symbol and then press X, X, LB, RB, X, X. If you did this properly a message will appear saying: Do you want to perform maintenance on your Xbox 360 storage device. Selet the “yes” equivalent and then boot up Halo 3) or any number of other weird issues like the host has TU2 and the client doesn’t or the client has TU2 and the host is on TU1, it’s going to be a bit like the end of Ghostbusters, but we promise, that even though it seems like Matchmaking has fallen into the gaping maw of cement cracks – it will climb out.

We expect all of these issues to resolve within four or five hours of TU2 going live. We will be watching it closely.

There’s a bunch of other stats-y things coming along at Bungie.net as well, so hop on over if you’re really interested in all of it.
