Not very long ago I got the idea of how nice it would be to have your Mii on the DS when I saw the Personal Walker Trainer on the Nintendo DS.
However, the Nintendo 3DS will or might have the ability to receive Mii’s from the Wii according to the news that’s been floating around on IGN.com.
Here is a quote about that: “IGN AU: When the Wii was launched, the idea of Miis and avatars was very new, and we're already seeing Mii games on the 3DS, is there going to be a way to transition your Mii from the Wii to the 3DS, and is it important to have that a persistent Mii identity across both systems?
Shigeru Miyamoto: We need to keep in mind how we evolve the Miis and how we think about compatibility with Miis between different systems, but that's something that we're definitely giving consideration to and want to continue to try to allow people to use their Miis on different Nintendo systems going forward.”
And here is a link to more data on all that.
