New to Diablo 3, Can i get ALL Achievements?

[nevalopo]

So if i buy a complete new D3 copy, Can i get all the achievements or are there some unobtainable because i didn't play at a specific date?

There are legacy achievments that you cant get anymore.

There are feat of strengths like in wow which are unobtainable, the rest should be possible.

You can´t get all AV´s then.If you killed Diablo on Inferno you got a FOS,and in fact the inferno mode doesn´t exists anymore you can´t get it.
