Back in the early part of this summer there was a rumor that Samsung would be launching the Galaxy Note 5 ahead of schedule in July to pre-empt the launch of the Apple iPhone 6S Plus. That rumor was later refuted by Samsung's CEO JK Shin. It turns out that the rumor was partially true though. Samsung will indeed be launching the Galaxy Note 5 early, but it will be in mid-August instead of July.
Normally, Samsung usually launches the Galaxy Note series during IFA in September. This year Apple shared they would be holding their iPhone 6S and 6S Plus launch 6 days after IFA. It looks like Samsung's strategy is to get out ahead of the next iteration of the iPhone Plus model with their Galaxy Note 5.
This way they can potentially scalp sales from the Cupertino company and keep some users away from the next larger iPhone. This accelerated launch schedule also allows Samsung to ramp up their hype machine to market their phablet-sized device longer.
