It's dsgusting really. And I stand by my original thought that he wanted a pairing for Sasuke first, then NH came later.
(And, as an aside, as Chatte pointed out, why bring in Karin so heavy at the end? Just as a plot device to heal Sasuke? Ugh. I was never a SK shipper at all, but I have to admit she had a point. And it would have worked well with the whole Yin/Yang theory. )
I think the truth is Kishi never cared about the romance at all. Not that he was a bad writer, he was just kittening with every ship he could. Then in the end he picked one to continue the series with.
The upside is that, you're right, he is detonating himself in a spectacular fashion. It's just a huge wreck.
I'm past the heartbreak of realizing it isn't going to work out, when the last chapters came out. Now I'm just in utter disbelief at how this whole thing is going up in flames. I suppose that some cold comfort at least.
I suppose it is, and it's likely a lot of people will be against getting any new works of Kishimoto-sensei's if he's gonna do stuff like this. All he said just makes my kitten detector go off... =/
