No. The ETA was April for the code to be released, not merged (!). There's a huge difference here and it seems like users do not know. The code is being thoroughly tested while also some missing pieces are being added. The last time that I was looking into this, the information pointed towards a release in Core 0.12.2 which is the next version.

much of the hashing power has already said they're not going to run segwit until a hard-fork is released
There's a difference between releasing code and merging it. From what I understand, the people that were part of the HK agreement are currently working on a proposal and it should be released in < 2 months.
