We are in for a long wait on getting back to the main story line.... I was hoping 312 would be the last filler, but for now, at least 315 will be a filler. I appreciate that they are intermingling Akatsuki with the filler arcs, but the young Naruto in fillers is quite aggravating. There is a huge difference in character development (and story line for that matter) between the fillers and the current story line. Add to that the drama, excitement, anticipation and revelation contained in the current story line and one can understand the disappointment in watching fillers.
