It must be Advance Wars related. The series is huge in Japan, with installments as far back as NES.
Given that there already has been a Nintendo 'Advance' hardware product, I doubt they will bring back that name out of sequence for a hardware item.
Of course this is wishful thinking on my part to some degree. I'd buy the game instantly on 3DS, or buy a WiiU early for it if it were a U title. The SNES game is pretty awesome.
