Hmmm.
I'm hoping that Obito was kept alive in the last chapter to do good on Madara's promise to use him, or why not just kill him outright? He was as defenseless as humanely possible.
I'm actually hoping for Madara's plan to work to some extent, causing massive casualties and leaving maybe a FEW strong Shinobi (Naruto and Sasuke included) which would cause them to go off and do some training together to confront Madara.
Would actually be a nice turn of events to see a villains plan go all the way through here, and since we know this manga is destined for a happy ending, it would satisfy the needs for a happy ending AND a plot twist with death.
