I think this is one of those things a lot of us would enjoy and appreciate, but I just don't think it is going to happen. Think of a time where you under-delivered something or messed up a project and had to fix it. Would you want people now to watch your every move going forward? I don't think so. Adds unnecessary pressure and opens them to (more) criticism. Additionally, I think the team at Guild Wars has something they are really proud of and they are happy to share that stuff. I don't think that is the situation here.
