Delixe: He still get's his name on the credits as lead designer but he was only lead designer on the PS3 and Xbox360 versions.
I don't know about that, haven't seen nothing to actually back that up.
From what i gather when Knowles decided he wanted no part of DA2, and we don't know why exaclty, he's quite vague on the whole subject without offering any real specifics, which is understandable, he stepped down from an active role as lead designer on the console versions even if he did stayed on for months after that, i'm assuming still working on the project just not as active lead designer on console versions anymore. That's as much as i can gather, which says exactly nothing about Laidlaw's participation on PC or consoles, but it's possible i'm missing some data on the subject
In any case DA2 is mostly on his head and some of his statements about the future of RPG's and such worry me a bit, i definitely wonder if maybe someone else should step in as lead, assuming there will be a DA3.
I only wish that if he ends up going he takes Silverman with him ;)
