I am curious why Nintendo hasn't pushed 6.3 out yet since gateway has been in the wild several weeks now...here are my theories.
They are letting people get there Gateways for Pokemon X&Y and BAM 6.3...Wait & see
I really don't understand the fascination with Miiverse or Mii's altogether. Ugly, annoying critters hijacking your screen are hardly something to look forward to, but each to their own taste I suppose.Maybe, just maybe, they are working on something else for the next update. Something like Miiverse and NNID - I can see Miiverse 3DS at least coming when Pokemon X/Y get released.
they are waiting for Pokemon and will force people to give up their gateway or else not be able to play it..
