I'm not expert on HD developement but I'd imagine the step up isn't something that will be irellevent in 10 years time even after the next consoles come out. It seems that the experience companies got from developing for the PS2 is being applied to make Wii costs much cheaper, albeit they're cheaper by nature but the point is still the same. It's again in similiar vain to the porting costs of PS3 to 360 and visa versa being much cheaper then one inidvidual game, the assets will all still be the same, just improving them, or whatever. Once the new systems come out they don't start all over again, unless whatever the PS4 and xbox 720 is something of an astronimical leap that we had this gen, which it isn't. They might need to upgrade engines or whatever but the core HD developement type scheme will be there. Of course I'm no expert so I'd be happy for anyone to correct me, don't think there are many articles on the internet about this.

The experience companies have from PS2 development is applicable to *all* current consoles. There is nothing magical about HD vs. Non-HD. This is experience in managing a game project, managing the flow of assets, etc. But nothing other than that helped out, certainly not technically, with the Wii. Except you might have art assets that can be more easily re-used. Now if you want to re-use graphics again, in 10 years on the PS4 then I suppose there will be some savings.
The expenses in a new generation are tied to learning new hardware, the API that's made available on the boxes, and general additions of things such as built in physics. A lot of these learning curves are present in the Wii, while some are not due to its Gamecube heritage.
The big expense re:HD graphics (I assume you mean graphics here, and not the other features of the HD consoles) is mostly a matter of size. The overall number of pixles has been increased by around a factor of 4. That means a lot more assets to be created. It means more detail is present, in textures as an example. This all has a cost in terms of time. A car in Project Gotham for the XBox might have taken a couple weeks to model... one in a newer version might take a couple months.
Most of your "savings" points deal with porting. That's re-use of assets, not something "learned" from HD development.
