The french leaker who made that tweet only did so after Navtra had already spoken about this title first on ReeeEra so we don't know if he/she was just piggy-backing off of her information or not.
What has this leaker actually broken news on first before anyone else?
Also there is a great irony here for the first few posters praising the leak in this thread, if the same leaker got the platforms wrong for Final Fantasy Origin then why do you take the platforms he's leaking here as a certainty?
It appears there is a trend in some particular threads where - instead of considering the validity of the information and adjusting their response accordingly would rather act like it is true because it is want they want. For e.g;
Thread about Demon's Souls on PS4? The reaction is "Oh yeah, that's definitely happening because *reasons* and it's coming to Y platform too because *reasons*". A day later it is debunked.
Thread about Sony and FROM SOFTWARE doing another collaboration? The reaction is "No way! That's just not possible." A day later evidence comes out of Reddit that makes it look practically verifiably true.
This is just an observation but they should make an effort to be more objective lest they have their expectations or hopes crushed for the 10th or so time.
I'm not saying this leak isn't true either, but what has this guy leaked with 100% certainty before anyone else has before? Navtra is someone with a practically impeccable track record.
