Prediction thread: How much will all the 3DS revisions combined sell?

[TheWPCTraveler]

So, we have roughly 45 million 3DS units sold through to consumers, huh?

Well, then: We can expect at least 5 million current 3DS owners to convert to a New 3DS.
Add that to a baseline of 10 million/year, and you'll get roughly 80 million sold lifetime.
