So Microsoft bought the PureView team to lock it all up and never use anything that was under development already ? They will throw away their biggest differentiator away because they want to make their other OEMs happy ? Ya, maybe... I can't really put anything past Microsoft.
They are certainly not winning in any other category expect maybe built quality in some rare cases. Having the best phone camera money can buy is one of the very few ways they can say "hey, here buy our products instead of the iPhone 6!" other than that, they really don't have much going for them.
Maybe they might bring something like 1030 who knows?
I am just saying. They even made partnership with Canon in case if you missed that part so its still a long way to go.
But sometimes I think this, nearly every x20 series has gotten a successor.
520-530
620-630
720-730 (coming at 4th September)
820-830 (same as above)
920-930 ( even some say this ain't but it is)
So this leaves..1520,1320 and 1020.
So WE MIGHT SEE A 1020 SUCCESSOR BEFORE OR AFTER 1520's...
But waiting doesn't help either too you know...
