3DS-NDS
This is essential the same battle the Wii just won against the PS3, but with a twist that Unlike the Wii the 3DS has a visual upgread with 3D. (a Curve ball to gain 3rd party) I dont really think slaping 3D on A portable Wii is Non-Nintendo like is it? Really?
I think the 3DS will outsell the NDS just like the Wii outsold the PS3. I dont think the market has totaly turned head over heals in the last year. so i expect the same results.
3DS price's and game price's will be the big factor of how many units they can sell in total. The games are a none factor in my thought prosess cause i know this things not going to get few-er then the NDS.
