New release of Endgame?

[norwich36]

Anyone who's seen Endgame with the new footage, (A) is at all at the beginning of the film, as a recent spoiler has revealed? (B)Is it worth seeing? (Potential spoilers in the comments, natch--and feel free to completely spoil me on this; I'm trying to decide if it's worth sitting through a third time, and if I do when it's safe to go to the bathroom, so i'm also curious if it's just the drector's intro and that one scene, or if they added more anywhere else). Oh, and I don't care about the spiderman teaser at the end since I'm going to see the damn film this week.
