I can imagine them being, not stronger, but deadlier. I know that's hard to grasp since the originals were so deadly but a reserve group that stayed in the shadows would have been bomb.
Let's just look at this war if Kabuto didn't miraculously show up and save Madara's hide.
-Madara "declares the fourth great shinobi war"
- Madara gets met on battlefield with boy wonder Robi-..Sasuke
-They both get sealed asap in some kind of way. That's the only way I see Madara losing in a battle. He needs to be sealed away.
@Kwasi- his trump card could be a technique to allow him to escape death (Oro had plenty of those) or that body that he showed which could be Naruto's mother...or.................................Obito
