What exactly is wrong? What is the source for that? From what I'm reading here a lot of these predictions turned out to be dead accurate to what was shown at E3 and revealed later, like Hunk and Tofu being planned as well (but back then it wasn't decided if it would be DLC or not)
Going through it in order:
Leno doesn't have the same background story, they changed it which is why some fans are upset.
Kendo isn't early in the game.
The "whole" locations aren't redesigned. A lot, if not most, are true to the original.
Pretty sure CAPCOM have said they have no new enemies.
Claire doesn't really look like OG RE2 Claire
Not sure what he meant by "different variation" in relation to zombies. All zombies are pretty much the exact same enemy type.
No female licker has been revealed let alone one that you continually meet.
Both Claire and Leno will face Mr X, not Claire facing the female licker.
Cutscenes are not real time, they're pre-rendered. At least from what I understand of the terms.
I've seen nothing that's revealed Ada as being able to kick to stun.
Alligator is in the game, he hasn't been replaced with a Bio weapon.
From what we've seen the Alligator is still met in sewer so I'm not sure how that's different to RE2 like he stated or a surprise.
Hunk and Tofu are in the base game, not DLC.
Game was never planned for holiday 2018.
RE3 is not going to release in holiday 2019.
Honestly the only things he got "right" were:
That it's OTS.
That they have different voice actors.
No Crimson heads.
No A/B
Ink Ribbons being difficulty linked
And again, those aren't exactly sticking your neck out guesses.
