Said it the minute, when they announced it is a prequel for PS3/360/WiiU, a not developed by Rocksteady.
Can't blame them though, Batman Akrham got very popular, they wanted to go with the punch and get more profit. It most probably won't be a bad game, just not the levels of Rocksteady's games.
But worry not, I'm sure Rocksteady is already well into development of another game, hopefully in Batman universe for PS4/X1 and it will blow our minds!
So it is happening...PS4 preorder.
Greatness Awaits!
