as much as i hate to say it i believe that sakura was lying. its obvious that she likes naruto but her true feelings for the time being are with sasuke. the reason she "confessed" her love was to put naruto out of his misery for him to stop chasing sasuke on her behalf.
for now sakura still loves sasuke, but i think eventually this lie will become a reality, but not until a certain event happens that will make it official to make sakura no longer loves sasuke
