Theory: Wii U is part of the fusion concept and will be around longer than we think.

[Soundwave]

I don't think the Wii U can be saved at this point.

There are other issues I suspect at play too like Renesas is the only firm that can make the Wii U's eDRAM and Sony owns them now.

So maybe Nintendo feels like they're not going to be able to make the system indefinitely anyway. If Sony chooses to stop making that type of eDRAM ... Nintendo is basically f*cked.
