As noted, Shane McMahon will wrestle The Undertaker in a Hell in a Cell match at WrestleMania 32. If Shane wins the match, then he gets control of RAW, but if The Undertaker wins then Vince McMahon gets full control.
Shane is already training for his match with Undertaker and posted this video on Twitter:
