Miiverse will be integrated into the 3DS by the end of this year, Satoru Iwata has announced in the recent Nintendo financial results briefing. While you can now access a limited version of Miiverse through the web, Nintendo plans to flesh it out specifically for the 3DS.
"This will facilitate user communication about Nintendo 3DS games and help users enjoy them more deeply", says Iwata. "At the same time, the more people that take advantage of Miiverse, the more deeply and correctly they will understand the charm of the other platform, Wii U."
Doesnt make sense why it would take that long........If I had to guess, they're probably planning on rewriting the 3DS firmware so Miiverse is integrated into the system, rather than it be its own separate app like Swapnote.
........So, if I have no Wii U... I should just forget about this..? :(I'm sure once 3DS service starts you will be able to create Nintendo ID account from there too.
So I can use my Wii U Nintendo ID on my 3DS? Does that mean unified user accounts???We're hoping as much.
