NaruSaku is far from dead. This chapter did add some ammo to the SasuSaku and NaruHina people, but don't say that NaruSaku is dead until the pulse stops. This is far from stopping NaruSaku's pulse; it already has far more support and development than it does arguments against it.
SasuSaku is not canon just because Sakura thought of Sasuke at that point. Are they together? No. So it isn't canon, and is far from ever becoming canon. Why? Sasuke tried to kill her, has done even worse things, and is on a road that he can never return from. Even if Sakura is willing, Sasuke won't ever be.
Let me clarify something here: I do not believe that Sakura has EVER loved Sasuke. All that I've witnessed is her having a childish, fangirlish crush on the popular boy. It's obvious now that she still thinks she "loves" him, but what she's feeling is not love. She's feeling the remains of that past crush and a strong friendship bond with him; she has a lot of stuff going on in her life right now (including relationship confusion) and she's not able to organize her thoughts...
Although, I will admit, it just makes her look bad that she hasn't matured enough yet to realize that she's chasing a childish crush and former teammate/friend with the mentality that she "loves" him.
