Call me cynical, but I still don't believe that you can clone a endless runner game, slap Mario on it, and expect it to be successful on mobile. I get that it's a big deal that Nintendo and Super Mario are coming to mobile, but as soon as the novelty of the news is off I think they'll face a pretty major reality check.
It isn't an endless runner. It has actual hand-crafted levels, like Rayman Jungle Run, which is much better than any endless runner I've ever played. With Nintendo's level designers, I expect it to be pretty fun.
It feels kind of like arguing about hacker and cracker.
