I don't think they've learned much. Nintendo is fairly stubborn with how they view the industry and with a predominantly 60-70 year old Japanese board of directors they will continue to do things from their POV. So they won't do a lot of the things people are asking for in this thread.
The main take away I think they've learned this gen is they can't support a modern handheld and modern console any more, next-gen they will integrate the two like the iPhone/iPad are basically the same hardware capable of sharing many/all of the same software titles.
Also I think the "Wii" and "DS" brands are both going to be junked by Nintendo after this gen and one new, more unified brand (for their portable and home variants) will be created.
