How many android versions long?

How many "major" android version updates is OnePlus 2 going to get, officially, from OnePlus?

Will it get Android N?

I read that OnePlus One struggled to even get a stable Lollipop 5.1 build, for a long time!
Anyway, atleast it is one of the officially supported devices of CyanogenMod and the others.

I've ordered my OnePlus 2, but this is the only thing that's worrying me.

Why no development for the LTE versions of the Tab S

Just curious?
Is it a lot more work w/ the cell modem?

Is there any difference between the EU and the US versions of this phone?

Hi
Is there any difference between the EU and the US versions of this phone?

- or they are both the same (hardware and software)/


Thanks
