Looks like it will take time before the release of Kingdom Hearts IV and no choice but to wait. I haven't really explored the KH3 and I heard there are still some more side quests, unlockables and secret ending? Can anyone confirm that? I just saw if from the Wiredshopper review. I haven't seen the Dark Inferno at all. ?

yeah the secret ending is really something else. there's also lots of fun side quests and mini games to do afterwards but the Remi's cooking mini game is a little bit frustrating I think. luckily I got the grand chef Keyblade. lol

Yeah there will be more side-quest and stuff when Kingdom Hearts 3 Re:Mind DLC is release next year on Jan 23, 2020. If you haven't play Kingdom Heats 3 or at least finish it yet than I say wait for the Re:Mind DLC, because Re:Mind is looking like a Final Mix version of Kingdom Hearts 3. But remember you need the actual game before you can buy the Re:Mind DLC.

Well, if you haven't played the game, I'd say you've come at the right time to play it, since Re:Mind comes out next month. After playing through all of it, the wait for KHIV luckily won't feel as long. And I feel that since Nomura and his team got the new Kingdom Shader engine down, they can use their assets to create more KH games in half the time it took to make III!
