As a college student, I do a lot of walking around campus (except not right now because I broke my ankle), so getting rewarded for it sounds pretty cool. The battery isn't an issue for me, since I'm in the habit of plugging in my iPhone and iPad every night to charge, so I'll just do that with my 3DS as well, and I doubt I'll be running out the whole battery in one day very often. That, plus the fact that I'm actually excited about the OoT remake, and that there are a couple Western-developed launch games that aren't on the Japanese list that I'm interested in, means I haven't seen anything so far that makes me consider changing my mind about picking one up at launch.
