Hearing people's reaction to the KH4 logo is extremely hilarious and precious to me. The ludicrous amount of time between KH2 and KH3 (KH3's announcement, really, let alone its release) really had a quite an effect on fans. After KH3 came out, I saw so many people saying that there was no way KH4 would get announced any time soon, and that there needed to be a series of games that could 'lead into' KH4, as though KH4 wasn't allowed to set itself up.
I'm not saying people were dumb for thinking that, but I definitely thought that it was a good time to just jump into the next one and introduce everything properly with a big new entry rather than a paltry series of spinoffs, and I'm glad the team felt the same way, because the reaction to that logo is so amazing-- Despite having spent the last three minutes looking at a game that was OBVIOUSLY KH4, they still couldn't quite believe it until they saw the logo. Only Kingdom Hearts, man
