Q: Where do you intend to prioritize allocation of your development resources going forward?

Q: What do you think of Nintendo Switch, and how are you approaching development efforts for it?
A: Nintendo Switch is seeing rapid uptake, and we welcome the arrival of such a platform. We intend to be proactive in our development efforts given that it’s a platform that is well suited to the mid-sized titles at which we excel.
