Just yesterday, a trademark surfaced for what appeared to be a newly redesigned model of the PlayStation Vita. However, that doesn't appear to be the case after all.
According to DualShockers, the "(位置商標)" in the trademark actually refers to a positional change of an element within the product rather than a modification in its design. As such, Sony's filed request isn't in reference to what many assumed to be the hypothetical "super-slim" Vita 3000.
According to Sony's full trademark listing, the registration is actually in reference to the three-dimensional position of the face buttons, not the shape or general form factor of the console itself.
With these new facts, it seems that Sony hasn't yet filed a trademark for a third iteration of the PlayStation Vita. That, however, doesn't preclude the company from revising its handheld again at some point in the future. If Sony does end up refreshing the hardware once more, what would you like to see changed and/or added?
We've reached out to Sony for additional clarification.
