Re: Phone size.  Everybody 
I know, personally, save one individual, when I've asked about the size of their 5.7" or larger phones, replied with something like "No, it's not too big," in a tone of voice that sounded like "but I wish it was smaller."  Other than that one person, nobody has ever replied "It's great!  I love it!"  Much less "I wish it was bigger!"  There was one colleague who insisted he loved his gigantic Note something-or-other.  But, as soon as his contract was fulfilled, he went with something 
much smaller, next time around.
I can understand how those of you that use your devices as media entertainment centers want large displays and walloping stereo sound, but many people, perhaps most, mainly want a mobile communications device that can 
also display/play media, rather than a marginally pocket-sized home theater system 
 
I'm, admittedly, biased.  For me, 5.5" is the very top end.  I can even appreciate the advantages.  But I prefer smaller.  Thus, and assuming these rumors are more-or-less accurate, I'll probably go with the Marlin's little brother: 
The Sailfish.
