Something is fishy still. Sarada do not have any of Sakura's features but have every feature of karin, even the hairstyle and glasses. I don't know, something seems kind of off.

I mean even Sasuke never denied it. Not to mention even someone like Naruto who knows all the details of the village and it's citizens was suspicious.

So I think the theory still has life in it. Not to mention plot twists are not that uncommon in naruto, like the "tobi is madara" which even onoki someone who fought madara thought tobi was madara.

So might be something like that.
