I'm looking forward to seeing what the results are. I'll make an effort to post during the 3DS survey, assuming I'm around. I'll likely post it in text-form, so it's easier for you...and also for me to refer back to later.
Not sure if it's information you care about, but looking at play-time for certain games might also be interesting. For example, maybe a certain game is bought/downloaded by everyone, but a good portion quit after a few hours. Of course, if you're only interested in purchasing habits and not play habits...then this really doesn't matter.
Anyways, good luck! Don't drown in all the data...
