I think to be fair to Ian Sane...he doesn't hate all Nintendo software. He loves the characters and the games. He loves the potential of Nintendo and the quality Nintendo brings even when the potential isn't met. Nintendo is still one of the greatest talents in this business.
However, Nintendo isn't the only talent or even great talent in this business anymore. And Ian's complaint about getting crap support for reasons Nintendo could have prevented for more foresight is valid. Nintendo has made many short sided business decisions that were great for business, but bad for their market...and eventually good business decisions that hurt your market position become bad business decisions.
Hopefully, Nintendo has seen that, and all indication is that they have and are working towards fixing it. However, gamers like Ian have a right to feel concerned about the issue, and still want Nintendo to succeed and root for Nintendo. There is still a reason to get a WiiU if there is a PS3 port of it. The WiiU controller may give better interface or new gaming options, the WiiU has Nintendo exclusives, the WiiU can allow you to play your games and watch TV, the WiiU will potentially have higher quality graphics.
And, if the PS4 isn't out for 1 1/2 or 2 years after the WiiU is launched that is long time of higher quality gaming on a Nintendo system than the rival. Plus, Nintendo may still be bringing better motion controls to the table with the WiiU.
So, I think Ian Sane is quite Sane in his arguments, and position...though I personally disagree.
