To me it's clear as day that narusaku is heading to canon, which is why they are teasing fans with a red herring (naruhina)
The 2011OVA is about to happen, next chapter in fact...the buildup with Narusaku is STILL ongoing, and it isn't going to stop until it's canon.
So, till that happens, and SS is dead, NH is the only ship they have to tease with...and it's working like a charm in the USA.
The Japanese fans must find this Ironic, to them...Narusaku is too obvious, but to us, it's going to be a shocker (well, to the NH peeps anyway...)
They like Hinata over there a lot true, but from what I have seen NH?....not so much.
While Sakura is both liked as a character (for a female in a shounen anway) and the pairing is very well liked.
The only reason SS was liked is because it's good looking, heck kakairuka is the most popular ship right? And it's crack! xD
So...er,...yeah, I don't feel worried.
