I'm not so sure the power of waking (atleast in the maner it was used in KH3) can really be considered a standard part of Sora's skillset. The game was very overt that what he did to revive his friends was a one time deal and if he did it again he wouldn't be coming back.
Now powerscaling wise he should be solidily above his KH2 self by the end and he is atleast presumably above a guy who can space toss giant monsters.
