I am not sure how Nintendo fear money. All Nintendo has done recently is (quite fair for a company) to try and maximise their profit.
Valve not releasing Half Life 3 is interesting. I think the reason they haven't is because the FPS has evolved quite a considerable amount since the last half life game. I do not see another Half Life game until this market starts to decrease.
Otherwise they would have made an FF game with a good story by now, like how Squaresoft used to.
They would have made KH3, FF7 remake, Chrono Trigger 2 e.t.c
over the FF13 sequels we got
