Yet, they release plenty of itterations for their handhelds.

No, the Wii without GC support doesn't count as a proper redesign ike ps2 to ps2 slim...

Maybe because they are already too small.
Btw, they redesigned NES and i believe SNES aswell.

They redesigned the Gamecube in 2004. Anyone remember the Gametrapezoid?

Nintendo should make a console as big as a grill and then make it smaller for people to have a reason to buy either a second one or for the first time since they can now fit it under the TV.

They perfect their design prior to release like every company should...

How can you redesign perfection lol

Because Nintendo don't design consoles to brakedown after 12 months... and need a replacement.

Why would Nintendo want to copy a insufficient setup. The lack of a need to redesign is a good thing. It means their consoles were done right from the beginning.

but they gain more sales which is good for business in times where you are loosing money! I mean if Nintendo had this planned out they would not have lost the small amount they lost with 3DS. think about it! ;)

Nintendo shouldn't be afraid of copying smart business moves

One thing that's really amazing is how small the Wii U is compared even to the slim (and super slims) versions of current systems. It's more powerful, yet smaller.

But I agree, they should do it. If only for a visual change, to spice things up
