Now that Tobi has been unmasked, and there is officially another living Uchiha besides Sasuke, will Orochimaru continue to focus all his hopes on dreams on Sasuke?

From what Kabuto said during his fight with Itachi and Sasuke, it would seem that Orochimaru was interested in becoming the next So6P. Wouldn't Obito's body be far more tempting to Orochimaru, since Obito is an Uchiha who already has Hashirama's cells (another thing Orochimaru was interested in) and a Rinnegan on top of it all?
