Well two things..
1st - Why does RDR2 hold the Meta record to you this gen when 2 Nintendo Games came out previous to it that hold the same score? If anything Zelda BOTW was the first this gen to achieve a 97 meta so that's the game to beat not RDR2 which only matched the record.
2nd - I cannot see any game this gen surpassing a 97 meta, maybe come close to matching it but not getting a 98. Too many troll reviews out there that will guarantee it wont happy. (I might be wrong) but I highly doubt it.
