You heard it hear first, Aussies are too big in the game to face any meaningful penalties so any sanctions given will seem too leanient. Smith will resign and just play as a batsman and so will Warner, coach will defend himself and most likely remain in his position (Bans and fines may be used against them however they will be minor). Smith's arrogance about the entire situation suggests he's untouchable and that nothing will come of it, maybe he's got the backing of the CA hence the swagger?
This story will be swept away quickly by ICC board, again because Aus are one of the key players and as we all know the ICC are corrupt money grabbers.
It's a sad state but I genuinely believe most will get away with it and in a year's time we will have forgotten about it.
