Definitely disappointing given that this is 14nm not 16nm like Nvidia.
However, I also believe AMD actually over estimated the TDP. I mean the reference card only has a 6-pin and gets rated at 150W, while the GTX 970 at 145W has a 8-pin for the reference. From Nvidia, we can see that 6-pin usually refers to TDP of ~120W.
If AMD specs is true, it would mean the reference card will have absolutely no overclocking headroom and will be making use of 150/150W available from the 6-pin + PCIE slot.
I believe at one point, the presenter did say "under 150W" so I guess they haven't finalised the final rating for the reference.
