I feel like this E3 was sort of the straw to break the camels back. The Digital was pretty bad but it wasn't that bad. Not bad enough to warrant the fandom meltdown it has caused IMO anyways. But after three years of sticking with a console that has little to no third party support and is plagued by droughts, questionable Amiibo practices and game delays this direct gave us nothing to latch on to, nothing to get excited about. They only needed a proper Metroid or just something new awesome and unexpected, some sign they still care about the WiiU in the future and they'd probably have gotten a pass yet again.
As it is it at least feels like they're abandoning their most loyal fans on a sinking ship. Maybe it's misjudging what they have. Maybe they do have things in the pipeline for WiiU. But even if they do, they did a very poor job with this presentation, sending exactly the wrong signals at the wrong time with this.
