yes, this is exactly what i want to happen as well. it would be perfect. as naruto is now, there should be no fucking way sasuke should be able to keep up. unfortunately plot no jutsu will happen >_>
If Sasuke appears and beats Naruto in his ultimate current form, this manga will be a joke. There is NO WAY Sasuke can beat Naruto right now. And what kind of upgrade can he even get to tie/beat Naruto with all the bijuu power? Then how does Naruto power up even further to beat him? It would just get stupid at this point.
At best Naruto is totally worn out from all this and resting with no access to most of his powers and Sasuke shows up in full power and they are EVEN and put off the continuation of the fight for a bit while this arc finishes and then afterwards Naruto can trounce his ass. Maybe he can knock Sasuke to the moon and let Sasuke emo out there for the rest of his life.
