How is the 3DS really doing compared to the DS in the U.S? 3DS/DS sales gap~

- 3D is difficult to get into, most people get their eyes hurt the first time they watch the 3D, and they tend to avoid it
- Vita is doing bad partly because of that also
- In EU the crysis is stronger now, and last year in Japan when it was launched
- The 3ds is more expensive than the DS

OK?

Did you state that Vita is doing bad because of 3D or something else?  Vita doesn't have 3D

I believe the bolded was in reference to the 3DS looking like an upgrade to the DS rather than a new handheld, and that the Vita has a similar problem.
