To put it briefly, Xenoblade will finally be released on April 6th in North America. This is coincidentally the first day of PAX East, so I won’t be playing it, unless it’s at PAX for some reason.
There is also new Nintendo Zone content coming on February 6th, a Pokemon section with full TV episodes and such, as well as 3DS demos. Not sure if there will be different ones from the eShop or not. Find one near you here.
