Orochimaru would make this manga Epic right now if.. 
What if Orochimaru absorbed Obito in his current weakended state?

If he was to do this then we will see the following:

Orochimaru will have:

Kamui
Rinnegan
Mokuton
Stronger Senju DNA(White zetsu was weak)
Dragon Sage mode (Highly Possible)
Kabuto abilies (Highly Possible)
Complete Edo Tensei

Hints for why this is plausible:

It is no secret that Orochimaru was looking for an Uchiha

Reason being is cause he wanted a strong vessel as well as the sharingan. However, he was unable to get Itachi and Sasuke body due to them overpowering them through there eyes.

Now that obito is in a weakended state orochimaru could easily take control of his body AND get Rinnegan, Stronger Senju DNA, Uchiha DNA and the perfect Vessel for himself.

With the above mentioned lets look at all the subtle hints and information we have learned about Orochimaru AND kabuto now that He has been absorbed by Orochimaru.

1) Him deciphering the Uchiha Tablet
2) Him deciphering the Shiki Fuinjin
3) All Hashirama Abilities
4) All Nagato Abilities
5) Immortality jutsu which allows him to survive jutsu that should ultimately kill him (Totsuka, Shiki Fujin


Lastly the Benefits to Orochimaru absorbing Obito and becoming the main villain:

Orochimaru with an undying spirit and perfect vessel can literally use ALL jutsu even jutsu that would kill him
We could possibly see all Sage's techniques
See Orochimaru full arsenal of jutsu
Kamui from orochimaru
Mokuton from orochimaru
LOTS of Forbidden jutsu from orochimaru.

With a power house like this we could no doubt see everyone go all out to beat this guy.
