The answer is both yes and no. Sales will rise week on week on the week SO launches. It is a new generation after all and each new game should cause an uptick in sales. But I expect the uptick will be short lived with no lasting influence on hardware sales.
I do hope the xb one fanbase supports this game, if it turns out to be good. I fear for Insomniac's survival if the game tanks. It feels like ratchet and clank is largely played out as a franchise, even though I want more of it personally. Resistance is gone. So these folks need to find a new successful franchise soon or the doom hammer will fall on them.
Their presence on PS will be missed if they become a MS second party.
