Rumour Watch: Tyranid Psyker?

Very recently we had the following rumours drop onto us:

Via BOLS:

"BIG BUG" – Larger than Tervigon sized HQ unit. Oval base, hunched over, but wider. Has 18” synapse. Psyker 4. Prime version: Grants FNP and Counter Attack to Nids in 12.” Stats like Tervigon, except 2A. SitW  
  
Well, maybe some more clarity?

via Jared van Kell from Librarium Online:

The new Mastery 4 model I am led to believe is the Dominatrix, who, according to a more recent source of mine, will have access to the augmenting Tyranid discipline, which they said was called the Discipline of Adaption (I would add salt just in case on this one), and the Discipline of Biomancy. Essentially this guys job will be to make the surrounding Tyranids even nastier whilst acting as a fire magnet.

Add plenty of Salt.

Tyranids are looking cool though.
