How Long Before a 3DS Redesign?

Well they've been reported as reasons the DSi battery is shorter, so I assumed they would do the same here.

But another reason for a revision would be available methods to make the parts smaller and more efficient (very likely if the system volume picks up fast). Combine that with a stronger battery, and you have damn good reasons to remake the system.

Sure, reducing your BOM is always a good thing to do but you can do that with basic revisions.  Look how many the PS2 had.  19 or so.  But it had just 1 major hardware redesign.
