The only exclusive on XB1 that even remotely interests me right now is Dead Rising 3, and if history tells us anything, it's that 3rd party games on Sony and Microsoft consoles do not generally stay exclusive for very long, especially not ones with previous installments on other consoles. It could stay exclusive, but it doesn't seem very likely, and if it does, oh well, I won't miss it that much.
A new Alan Wake game is about the only that will make me consider getting the XB1.
