Hate to be the bearer of bad news but his wording here is actually very misleading in an unfortunate way.
He clarifies here

I think the phrase he should have used was "spiritual successor", not "follow-up", because now everywhere is reporting that he's pitching an actual sequel to Shattered Memories to Konami and getting excited.
