"new redesign" sounds like there was a redesign already, and that would be kinda early.
A redesign may be necessary if the projected sales for the 3DS were way (double or more) above what it actually achieved so far. Then there might be a realization that, while in the current form, the 3DS can be successful, to achieve the company vision (presumably success of DS proportions), "drastic" action has to be taken now.
