I think the 720 and PS4 will fail sales wise if there is no hook

i agree
Msoft is dead in Japan and strong in the US, Sony is popular everywhere but not the N 1, well except maybe the EU, Japan is Nintendominated
i think the 3 have a real challenge this upcoming gen, but i think Nintendo has the advantage, because of its family friendly image, cheaper prices and the timing
