Note 5 and S6 edge Plus may cannibalize each other, as August release is tipped again

Now, more sources have apparently confirmed for Korean media that Samsung has indeed pulled the Note 5 announcement for August, but the concern is that this is the same month when the rumored Galaxy S6 edge Plus was supposed to be unveiled. The S6 edge Plus is expected to be a larger, 5.7" variation of the edgy flagship, while the Note 5 would set itself apart with the S Pen stylus functionality.
The problem, according to local analysts, is that the two handsets are expected to sport the same or very similar screen diagonals, both with 2K resolution, and might cannibalize each other's sales, rather than make a headstart against the iPhone 6s Plus that will be released about a month later. What do you think, could this eventual Samsung strategy for announcing the Note 5 earlier alongside an S6 edge Plus backfire in the end?
