LKD: NOA source has told me that Breath of the Wild will be a launch title, Stealth from GAF has also heard this

Recently infos saying that Zelda BotW actually probably will be launch title.

Recent things have come to light and I am pretty confident that Zelda is going to be a launch game on Switch. At least that is the goal.
