there is some kind of twitter drama around that "leaker", let's point something about it:
- whenever you see/read about a leak, especially on reddit and twitter, always take with a grain of salt, as it is said. most of times, those leaks are pure speculation or lucky guesses, especially without documents proving them
- if you want to have more reliable information, check reports of publications like WSJ and Nikkei, or just read the developers interviews and wait for any official information
- regarding that Persona leaker, probably knew some overseas Atlus staff (most of times, overseas Atlus office take care of english translations of most of Sega titles and "can" have some interesting information)
- with that being said, the part about Project Sekai is mostly true (there is even the website under development), but some details are inaccurate and outdated
- for the other leaks, I could say only 2-5% of those were true, other were only speculation or false information
- in this regard, I could say there are 3 kind of "leaks" in general:
1)speculation/lucky guess/partial information from some sources (some staff but not at high level)
2)marketing leaks: those do exist, sometimes companies run some "leaks" for some free marketing
3)controlled leaks: these can happen and bring trouble, and are made by higher level staff, with a mix of true and false information, to check and find out who is the person that is giving out that info.
