Got this piece of news from wow.com:
We killed Venoxis in Zul’Gurub and, upon being saved to the instance, noticed that we now had the option to extend our raid lockout — that is, to make it last twice as long or until the next week’s lockout would end.
This means that, if your casual guild is a scrappy bunch working on Ulduar, but you can only get to Mimiron each week before the lockout expires, you can extend your current lockout into the following week to get more practice on the bosses you don’t get to see as often.
Now — ostensibly — once you’ve done what you need to do with your lockout, you can actually remove the raid lockout extension and use your current week’s lockout too. We haven’t gotten to try it yet, but it looks like the functionality is there. Pretty cool!
We’ll wait to see what Blizzard has to say about it, but this is great news for smaller or more casual guilds who really want to clear instances and don’t mind less loot per week.

I have really good feelings about this. If there were not the option to begin on your current week’s lockout after finishing with the previous weeks, I may have initially felt a little less about it. I think for a lot of guilds out there this will give them the means to get to cracking on things they may be missing out on.
I know in our case, running a 12 hour raid week, It will be nice to have the option to extend it if it is ever needed. However, I might add I highly doubt we will use this service, being that we do run a 12 hour raid week the next week is usually “Buck up and do it faster” as opposed to “Here’s a cookie, try again.”
All in all some good changes coming it seems!
