Witcher 2 on Xbox was published through Namco Bandai, if I remember correctly.
Problem with some publishers is that they like to get their grubby hands into the mix and eff shit up. I understand seeing as they are attaching their name to it, but sometimes they go so far as to change important aspects of the game and take away from the dev's original vision.
I'm pretty sure most pubs are guilty, but some less than others. I just hope CP remains as envisioned.
I'd personally hate to see Bethesda get their dirty little hands on this and turn it into another 'Mainstream' RPG just like they did with the Fallout series but thats just me.
