Sony did it, what should Microsoft (Xbone) and Nintendo (WiiU) do to make a comeback?

Microsoft could buy Valve and bring Half-Life 3 as an exclusive. Or they could just start to throw away XBoxes dirt cheap, like 99 $ or something. Both options would be horribly expensive, but there's no way they'll make a serious comeback this gen without major losses. They should just concentrate on the next gen for gaining market share while still delivering for their fans on X1. When you know you have lost, you just need to let it go.
