All we were getting from Mario Maker was Japanese information. We had very little English information.
Also we do have news. The English Nintendo website.

The release date is still October 23rd. That is a done deal as they have likely started printing copies. They would have no choice but to have released information on the delay sooner. Because guess what? Within 2 weeks review copies will be sent out to every major gaming media outlet. This game will have to come out, and there is nothing Nintendo can do about it. This isn't Star Fox, where the release was at least 2 months away. This game is already printing and being prepped for release.
Furthermore, the Treehouse is known to be wrong. Time and time again. Especially within livestreams. They are under pressure, so they get facts incorrect. For example, in one of the NoA livestreams fro Xenoblade Chronicles X, they stated that you can only play as Cross the entire game. That is so incorrect. They are on livestreams though, they can very well be wrong.
Are we also really surprised that NoA is incompetent at advertising? Really? Like I said, they didn't show off any of the overview trailers until around 3 weeks until release. That's just the way things are. Quit being so melodramatic and creating a problem when there clearly isn't one.
