We've received another bit of info from a very long-time reader. This reader has been spot-on with previous information, so I'd take this new info seriously.
Our source says that Nintendo of Canada reps are going to be attending a Wii U conference next month, but it's not the NYC one we all know about. Apparently there will be another conference in San Diego. I'm guessing this one is for Nintendo reps only and is not meant for press.
