Babylonia Release date? And TGF NERO

Finally finished Camelot!(Without revive! Yes shocking!)

Best story so far with its unfair bosses.
Heracles lvl 70
Shuten Doji lvl 60
Mash lvl 40
Saberlot lvl 40
Kintoki Rider lvl 40

I just want to say THANK YOU FATE GO FOR GIVING US NERO CLAUDIUS! so OP at last boss
T^T the BEST episode BTW

So here is my question, when will babylonia be released? And will there be another difficulty spike then? I probably need to buff my chars by then

Sorry for the bragging ^^
