I think Cena and Lesnar were the obvious two choices, but hearing Rock's name be thrown into the mix is interesting. John Cena - I think this match will be saved for Wrestlemania 30, just because WM30 has the whole ten year anniversary going for it, and this is the biggest match that Taker can have at WM at this point. I also think this could end up being Taker's retirement, making Cena his last victim at WM30 and stuff. The Rock - Now that Rock is gunning for the WWE Title come the 1000th Raw, that means IF he is at Wrestlemania next year, he'll be involved with someone else other than the WWE Champion. He said he had to come back and beat John Cena to go down as the greatest WWE superstar ever. Then he said he had to win the WWE Title one last time to become the greatest. Maybe he'll do that, and then say to officially become without a doubt the greatest WWE superstar ever, he has to do what no one has done, and that is be the one to defeat the Undertaker's streak. Maybe he'll even make the challenge on the 1000th Raw since Undertaker is rumored to make an appearance there as well, and they'll do an almost one year build for this match. This angle and match is one I'd love to see. Brock Lesnar - This is the most likely opponent for Taker. Brock is leaving after WM and since the WWE would love to do this match (they tried at WM27 but Dana White wouldn't allow it to happen), this would be the perfect way for Brock to make his exit, becoming another victim to Taker. So, I think Lesnar is the most likely opponent, and I can't think of anyone else that Lesnar could face if not Taker, unless they manage to build Ryback up very well by then (that means the Goldberg chants will have to stop) and have him go through Lesnar, that could be great. (Or just lose to Cena again.) But on a personal level, the angle with Rock saying there's one last goal to accomplish (beating Taker's streak) to go down in history as the greatest WWE superstar ever is the most interesting for me.
