Lol you saw in the manga scans here is one thing If Madara gets Obito Rinnegan Sakura and Obito will die and Zkisji isn't gonna kill Sakura so instead Madara is gonna grab Sasuke eyes similar to what he did to Kakashi
Lol thank you somebody is finally seeing what I'm trying to say. Sasuke eyes is powerful than Madaras so it would make more sense if Madara stole Sasuke eye to full fill project Tsu mo ki
