they don't need a price cut! they have almost 50% of market share over the rivals, one of than have a 1 year advantage, and when you compare X1 and Ps4, Ps4 lead is something like to 80%!
the gap is groing, Ps4 is winning, why sacrifice profit? Ps4 will seat in this 70-80% leading diference all the gen, perhaps even more, and will have something like 60% of marketshare easy on the long run.
Prediction: In 5 years Nintendo will Lauch a "Core Mario game" very similar to Astro Bot. That said, many will Ignore Astro Bot existence and say Nintendo created this concept.
