Warning - HW2 Theater glitch that spoils the ending (No spoilers in this post)

In the Theater section of the campaign menus, it shows the cutscenes I've unlocked, but also, to the left of the first cutscene, what looks like the final cutscene.

It has an image from the final cutscene and a description. Very spoilerific :(

Edit: this appears to have been fixed with the 2.8GB update. A shame they couldn't get that update out before the US release time!

Edit 2: fixed for some people maybe, but not for me, it's still there.

Edit 3: finished the campaign now and yeah its a huge spoiler that ruins the post-credits. DO NOT look at the Theater before finishing the campaign in case this happens.
