my theory is the ports are aimed at casuals. its a easy way to introduce these people to nintedo's core titles (also more likely to buy with budget price). This way they may be able to convert casuals into core fans, increasing sales of their big franchises. the msot obvious one being pikmin although also metroid. whether we get wii sequels to donkey kong or anymore mario sports titles i dont know.
also you theory makes no sense. if they wanted to give help third partys surely they would delay punch out/S&P2/Trace Memory/ whatever else they are releasing Q1, in order to give more sales to the likes of madworld, little kings story, house of the dead and fragile
