An analyst group called Screen Digest is predicting continued success for the DS in the future. We do the same thing, but when they do it, they use specific numbers, and people believe them. Their craziest number? They are saying that in the distant future of 2011, 89% of Japanese households will own a DS.
They predict that by 2011, the DS will have an install base of 112 million systems worldwide, versus the PSP's 67 million. To put that in perspective, the Playstation sold 102 million units, the GBA has sold 79 million, and the NES sold 61 million. We personally hope the DS continues to dominate, because we love our jobs the system.
