There are 12 games that are " Secret games" lol
Also the list that seems out of place is this one

Most of what's on there is correct, but what I don't get is why put something on the list if it's not confirmed? If KH3 is there with a "No confirmed" tag on there, then FFXV should at least get the same treatment as it's a AAA title, there is no way that could slip under their radar for this long.
Unless it's another SE telling people to not say a word about FFXV ( which includes even mentioning FFXV lol).
