Cena will be around a long time yet, unless some catastrophic injury forces him out. I think ending Taker's streak would indeed be another mile post for the guy's reign at the top, and he still remains a top draw. It's old school to have a guy leaving put over the guy remaining. Triple H's career was winding down as a rassler. Brock's there as a part time attraction.
Cena's still money for them. It continues the legacy for this character they continue to market. It's another torch being passed, just as Rock did to Cena last year. Anyone that takes the title away from Cena seems a bit more important for every legend that passes that torch to the guy.
Sentimentally speaking, I could see them having Taker's streak remain intact. He's been that loyal and good to them. Fans might like that as well. But considering they're selling the idea that the streak is all that keeps the character alive, the logical conclusion could be the end of the streak.
