No problem.
Again, I agree, but I don't think it's a new frontier at all. It was already explored with the Wii, just not to its full extent. I'm sure there was still room for growth in that area on the current Wii, but hopefully (and by that I mean I'm a bit pessimistic) Nintendo will go back to it with the Wii U.
Nintendo is essentially the only developer I can think of that ever pulled off edutainment throughout multiple products. Before the DS and the Wii, education software was niche at best, and everyone thought of it as a joke that could never ever work on the market (including myself). You only have to remember the fad of kiddy pseudo-games for computers in the 80s and 90s. Nintendo understands how to do it better than everyone else in the industry.
