From what I can tell from looking at the t11 sets, it looks to me that the belt, bracers, and boots all match the other 5 pieces.
Now the question is, would people like seeing the 8 piece sets come back, or are they content with the 5 piece sets from Wrath?
And yes, i saw they only have a 4 piece bonus, but that doesn't mean there's 8 pieces of gear, remember, t6 from BC had 8 pieces, but only a 4 piece bonus.
