Three crazy things i'm writing apart because i'm not expecting them:
-FFVII live demo plays, shows a November 2017 date at the end (no way lol)
-Bloodborne II announced (i think they'll release a new multiplat IP in 2018, BBII is '19 IMHO)
-New Japan Studio AAA project (the JRPG dream lives on, even without Verendus lol)
