I really enjoy the war, so I hope it doesn't end soon. Also, ending the war means ending the main plot the series has been running on for the last 8 years, and since I like Naruto I want it to go on for a while.
But that said, I don't expect it to end too soon. The Juubi has at least one evolution left, and Obito or Madara have yet to become its Jinchuuriki. And I don't think it will cut back to that battle until the Hokages and Sasuke have had their debatte. If Sasuke and Co. join the battle at some point after that, it will be even more expanded.
