At a Q and A session Miyamoto spoke about DS games he planning in the future. One which can be played in the home (possible related to the DSi XL home focused approach) and one that has a greater focus on using the title in sleep mode. Along with those hint’s Miyamoto also said “Also, I’ve recently been caring for cats. That is all.” Satoru Iwata followed Miyamoto’s comment up with “He just gave a big hint.”
The first thing that probably comes to everyone’s mind is making a Nintencats game. I’m not exactly sure how many people actually want that, but I’m sure it would probably sell decently either way.
