Realizing this is the "wild dreaming" thread - I'd like to see more discrete followups.
(Knowing the names are likely in flux):
920 > 930 > 940
1520 > "1540"
1020 > "1040"
With specs/design to match. If they want to unify the design between them all, that would probably be interesting.
But a regular flagship, phablet flagship, and 1020 successor should be distinct, spec wise. Obviously plenty of overlap in some areas.
[And would it too much to ask for a 940 Mini that runs neck and neck with the full size one, possibly a top notch 720p screen and slightly smaller battery being the only concessions?]
