Spawn Wave is the same guy who leaked first info on Elden Ring way back in March. He is referenced in this gematsu article: https://gematsu.com/2019/05/george-rr-martin-ive-consulted-on-a-video-game-out-of-japan
So he has credibility.
Also consider that the engine would be reused and many assets since its largely the same setting story-wise. So it wouldn't be far fetched for a REmake 3 to be pumped out in ~18 months of dev time.
