Implications of DS being flat in it's fifth year?

[Nintendogamer]

Remember DS had a luke-warm start too, it didn't take off amazingly, even the PSP was ahead of it at the beginning whe nall of a sudden DS is more than double it's sales! Nintendo has really expanded the market, and I expect DS sales to hit 200 Million sometime in 2015. 250 Million is even possible if some miracle happened, that would happen in 2017- 2019.
