I heard that the chapters 402 and 403 are going to be longer chapters and have more pages and 403 is suppose to be the end. But who knows leaks could be wrong anytime of the day.
But this is the final arc. So after this match end the manga will end too.
Haikyuu isn't going to end yet, I believe, becuase on Chapter 374, when Oikawa and Hinata met, Oikawa said something about beating them. Which means there will be an international fight between Argentina and Japan.
