People wonder why Nintendo would release a DS2 when the DS is doing so well..... if it's in every Japanese school as a student aid, entering Japanese businesses as a training tool, and 1 in 3* Japanese people already have one, why not release the next generation that is sure to be adopted by this massive audience though product placement alone?
Nintendo needs to take this opportunity to insert the DS into people's everyday home/work/school life and start giving out subsidies for DS2XL units to schools and businesses as student/teaching aids and by making the successor to the DS powerful enough to run a wide range of applications, not just for the games they want to make today, but for all the things they will want to do 2-3 years from now too.
