It is a known fact that WWE superstars are not re-scanned for each and every game. Normally, previously scanned character models are used for a game. Just the fight mechanics and particle effects for the characters are updated for each game.
That being said, since the superstars are being re-scanned for the upcoming game, it can be assumed that the developers are leaving no stone unturned to bring about a significant improvement in its graphics department. Apparently, an advanced graphic engine would be used for WWE 2K17 and if indeed it happens, chances are that it might not release for the last gen consoles of PlayStation 3 and Xbox 360.
It has been confirmed that WWE Superstars Bray Wyatt, Brie Bella and Alundra Blayz have been re-scanned for the game. So it is quite certain that these superstars will be present in WWE 2K17.
Some previous reports claimed that Chyna might be included in the roster of the upcoming game. Chyna passed away in the recent past and many are of the opinion that keeping her contribution to the WWE business in mind, she should be included in WWE 2K17.
WWE 2K17 will hit the market some time later in the ongoing year.
Stay tuned for more update on WWE 2K17.
