Given Mark Hamill's age and Luke's inexperience with other Jedi, I doubt he'll be as powerful as Yoda. Yoda was 900 years of age and a member of the Jedi multiple times the life span of any human that entered the Jedi lifestyle.
I also hate that they're trying to push Rey as the most powerful Jedi ever, completely omitting Anakin & Yoda from the equation.
