I get the feeling they scrapped the raid for HoW. Let's face it as far as raids go in the mmo world Crota sucks. VOG is a solid raid however. Originally HoW was supposed to drop in March with a leaked raid in the reef planned. With the nightmare that Crotas end is they probably said screw it and push it till Comet comes in Sept. Then they came up with this Battle Arena, which sounds interesting, hence the delay till May 19
