Nintendo of America's George Harrison recently discussed a range of Wii/DS issues, from the various zapper related projects from third parties to Wii Ware, but more interestingly hardware revisions and third pillars.
An extract from the GameDaily interview:
BIZ: I interviewed Perrin during D.I.C.E. and we talked a bit about how Nintendo likes to revise its handhelds. I asked her if this revision model was applicable to console hardware like the Wii as well, and she said, "Sure. You'll see the ways in which we do that." That seemed like a strong hint that Nintendo will revise the current Wii hardware. Is a new model planned?GH: It's interesting, console hardware has always historically been on a sort of fixed, sequential pattern almost every five to six years and it takes you about five years to develop a new piece of console hardware. The handhelds and portables, like Game Boy and now DS, we've always been continuously innovating, and whenever we feel like it's time or have an upgrade, we'll do it, whether it's an improved screen for the handheld or slimmed down like the DS Lite
