There have been rumours that The Undertaker won't return to accept Bray Wyatt's challenge until Wrestlemania itself. That's completely pointless, especially as fans already know that the Deadman will be there (Wyatt is hardly going to come out on the 29th, call him out, and then return to the back when he doesn't show). Even just a single appearance on Raw would help to increase excitement around this rivalry, and it's desperately needed. Wyatt was made to look strong in his feud with Dean Ambrose and at the Royal Rumble in preparation for this showdown, but it feels like his promos both before and after the big reveal at Fast Lane have been going on forever, especially as he's so rarely been seen in action as of late. WWE.com recently indicated that Undertaker might show up on Raw, and hopefully that is indeed the case, as this is one storyline which could do with a boost.
