Right off the bat, I want to stress that we are unsure if this information is legitimate. Any rumor should always be taken with a grain of salt, but when a story like this pops up around April Fools' Day, it makes you wonder even more. As long as you have those thoughts in mind, let's continue on to the story itself.
Word is going around that Nintendo may have suffered a virtual intrusion. Apparently someone has been able to hack their way into one of Nintendo's development servers, and they've gained access to a few tidbits of data in the last few days. This would not be the first time something like this has happened, as another hacker gained access to Nintendo's development side of things back in 2016.
We will not be reporting on the content sourced from the hack, as that just wouldn't seem right. I also want to point out that all the Mario-related discussion and rumors that have been shared recently do not stem from this hack. This is a separate instance that has given new information. It's very likely some of it you've seen/heard about already, and some you have not.
We've reached out to Nintendo on the matter, and we'll report back if they provide a statement. We did not ask about the validity of the content pulled from the server, but instead, the hack itself. Hopefully the story is completely made up.
Thanks to Andreslop24 for the heads up.
