A link on Nintendo's US site shows Inazuma Eleven under 3DS with the text saying coming soon. Hopefully this means the US will get a new Inazuma title, though nothing is announced it's most likely to be Inazuma 3.
This title launched a couple of months ago in Europe and has an enhanced version coming out this year.
As an Inazuma fan I hope you will enjoy the title as much as I did and hopefully we will see the GO! Series out soon
