DS Redesign: If not now, when?

So the DS redesign was a rumor. Next-gen writes: “Rumors have been circulating the Internet regarding a sleeker, redesigned DS in the same vein as the GameBoy Advance to GameBoy Advance SP revision. While expected eventually, Nintendo said that a new DS model won’t be coming as soon as rumors indicated.”

If not now, when? Let us all summon the collective goodness that is the Infendo community and predict an usubstantiated guess.
