Rusev and Lana

The new WWE Superstar to emerge is Rusev with his manager Lana.
Their gimmick at first is annoying that every week they show up and tell something no one can understand but now with the Russia gimmick, things are getting interesting.

With the current situation about Russia and the world, the gimmick is perfect, it catches my attention every time lana say something about USA and RUSSIA.

But here is a thing, how long can this gimmick last? or how long rusev and lana last in the spotlight?
Because same thing happen to Ryback, Fandango and other new superstars.

I hope they continue the gimmick with this russia thing and they cross path with Zeb Colter. That would be great!
