McQuaid explains that the new development team will be working as volunteers for three main reasons: There's no money to pay this new team, McQuaid doesn't want to go through the same stresses that were involved in putting together the last remote team, and as the team will also be remote, it will require a certain amount of adjustment and uncertainty. If you're still hoping for the game's eventual release, you should take a look at McQuaid's full update on the official site.
