I think it's pretty clear that I was right here? I was suggesting that Persona 5 is competition for Yakuza's sales range, rather than RE6. That is 100% true. Yakuza 0 selling less than expected doesn't impact that because it just means Yakuza has further declined, like I accounted the possibility for. Persona 5 is not going to remotely touch 600k. It's not in the middle of anything. It sits perfectly in the 400k+ bracket I laid out there. When Yakuza 6 comes out in Dec, it will be competing with Persona 5 for a place on top PS4 sales, but by then FFXV will be heads and shoulders above both. Persona 5 won't outsell MGSV either, which is another example of a game that's outside of that bracket.
Well the original point was about Dragon Quest Heroes, a 800k title including digital, and how Persona 5 (which will be somewhere between 500 and 600k with digital, not including budget/expanded rerelease of course) is not that far because the mid range titles tend to dissapear.
You argued Persona 5 would be more in line with the Yakuza series because back then Ishin selling less than the main series was because it was a spin off, yet Yakuza 0 failed to sell more than Ishin (<400k).
Now we could say Yakuza 0 underperformed because it was a prequel, but Kiwami didn't set the charts on fire either (and it was a full blow remake I think ?) so can we really expect Yakuza 6 to be back in the 400-600k range ?
Tales IP also seems to be in the same situation than Yakuza.
If anything it looks like 400k is the new ceiling for mid range titles (Yakuza, Tales, Call of Duty, Battlefield) and that above it you only have the big IP (FF, Dragon Quest, MGS, GTA) and... Persona even though it's clearly below these 4.
