No notations on it about when it was going to open just that it was coming.

Reports are that it will be operated by TAV PrimeClass so no guarantee it will will be a *G lounge (could be) but they (TAV PrimeClass) participates in PP so hopefully it'll at least have that.

If it is *G you can hop between the two lounges as much as you like with your ticket (same process as atany airport with multiple *G lounges if you are eligible to enter - they just scan your boarding pass and give it back - sometimes they ask for credentials if they aren't attached on the ticket but usually not an issue).
