Yoshida: For our current update schedule, we’re aiming for large updates every two and a half to three months. We pretty much already have our schedule solidified up to 2.3, and then if everything goes well we hope to have an expansion at around a year and a half after the original launch. That’s what we’re looking at, but then again you know how things change. We’re going to have a big launch and a lot of content at launch, and a lot of people on the team are working on this as well. So, we’ll have to see how things go with the launch but that’s what we’re looking at.
