Are you talking about Persona 5 for Rintendo Rwitch?
Oh well, guess i am gonna write what they said. Just remember, take it with a HUGE grain of salt. It's not mine and what they said was never verified.
SMTV (this was posted some time after the reveal back in NSW reveal)
- Game started development as a PS4 title
- Later it became a PS4/NSW game
- Last he/she heard about it, Nintendo was trying to secure some kind of a deal...
P5 Crimson/Re-release/whatever (this was posted during the August concert where P3/P5 and PQ2 was announced)
- Coming out in 2019 or even later
- Early in development
- At that time (summer 2017) the game was being developed only for PS4. Could change in the future or could stay exclusive. His source only mentioned PS4.
- Hifumi will be a party member and join the phantom thieves
In general, nothing that can't be made up. Anyone could come up with these. The only thing that seemed odd at that time, was that P5 enchaced was going to be released in 2019 or later, which seemed quite far for a rerelease but now it seems totally possible.
Was it the one where the dude said it was planned as a PS4 game but Nintendo paid for timed exclusivity or something?
Yep
