Naruto Manga 490 is Out for Reading

The summary of 490 Naruto Manga

Kabuto: My goal is Sasuke-kun.
Madara: And what if I refuse?
Kabuto uses Edo Tensei to summon another coffin. The art is obscured so we can't see who's in it.
Madara: T-this is... How did you get this?!
Kabuto: This means there's no way you can refuse me.
Madara: Fine, you can have Sasuke after the war is over. Until then I won't let you see him and you will be watched. Is that okay?
Kabuto and Madara join forces.
Scene shifts to Naruto and talk about Kyubi.
Ends with Kisame spying on the Kumo meetings.
Kisame: Now we know Kumo's current military strength.

Maybe Madara's body is in the coffin?
