@fastyxx: Maybe you should share your in-depth analysis with the 3rd parties, since they seem to disagree. Besides, what you are suggesting, is crushing the whole model of how business works. 3rd parties aren't going to wreck their profitable ventures for the reason Nintendo might beat them in sales numbers.
Besides, looking at the situation from a single 3rd parties perspective, it doesn't matter who sells the biggest number, since they all are in the same market and before you release your first game, 100% marketshare belongs to "outsiders" anyway. There's no such single instance as "3rd parties".
Ok, and if we look at PS360 best-sellers lists, how many non-first party, new IP, non-big publisher games there is?
