It’s important to note that all of these discussions will be focused on the game at the time of the chat, rather than being predictive. It’s almost inevitable that certain forward-looking moments will happen, of course, but those are the exception rather than the rule. But if you’re mostly concerned about getting to find out more of what’s going on behind the scenes and why, well, you’ll have your chance next year starting in February.
Guild Wars 2 developers arrive at your home unannounced to talk with you about various issues with the game? Probably not. Thankfully, that is not what the development team is planning for next year; instead, they’ll be hosting a series of forum chats running for about two hours, with members of the team stopping in to talk with players, answer forum threads, and generally provide insight about the state of the game.
