Actually it's not. We stated repeatedly to the press (I know, I was there and actually typed it out in explicit detail) that the in game screen we showed them at the time of their preview was place holder and that the turbine point icons on the left hand column were entirely place holder art and would be replaced in the next build. Which we sent them a screenshot for.
THIS is the correct screen shot that we sent them after the tour. The skills on the left unlock as you progress through the trees. They're not gated by Turbine Points.
The housing update is not part of the expansion. That doesn't mean we aren't still planning on making changes this year (after the expansion launches).
