Polaris and Pascal are on Samsung's 14nm and TSMC's 16nm, respectively, FINFET technologies and they come out this year. Both have working silicon already. It's not the case that they'll only be seen in another year like you just said. However, everything else you said is correct (I'm pointing this out so no-one assumes I've just disproved everything else you wrote, even if they're DJBarry).
