I think I could actually see 110-130 million depending on how long Nintendo extends its life by keeping a steady stream of games going, releases a new model, etc. I believe while this isn't a Wii type explosion phenomenon, it'll be more of a slow and steady burn with a longer shelf life, and being part handheld, will tap into that larger DS/3DS audience.
