If 3DS Sells 50Mil Worldwide Lifetime, Is This Considered A Success/Failure In Today's Market

[CommonNinja]

considering how much the original DS sold, I would say 50k life time would be a failure.  I expect it to hit 50M before this year ends, and around 70-75M lifetime.

I think Nintendo won't anounce another handheld until next year as they will want the 3DS to get at least one more holiday of good sales.
