What looks better to a consumer buying the next home console from Nintendo? Nintendo, the platform holder who couldn't make Wii U succeed so they dropped support within three years of launch (and who cut the 3DS price massively after launch)?Or, Nintendo the platform holder that continued to bring their biggest, best titles to Wii U despite a small userbase?
What's a better bet for publishers and consumers? A platform holder who stands by their hardware, or a platform holder who runs at the first signs of trouble? If publishers and consumers are going to invest in new Nintendo hardware, Nintendo's decision to stick by or drop Wii U prematurely will play a major part in how well their next system does, at least initially. There are a lot of other factors Nintendo will need to nail, but sticking by Wii U and grinding out profit is far more sensible than dropping the system prematurely.
