Yes, next proper Metroid "Prime" will be on NX, that doesn't mean that the people at NCL aren't working on some sort of Metroid themselves, some sort of non-first-person shooter adventure game. I don't mean that whatever NCL is working on will be on Wii U though. Perhaps Nintendo SPD is maybe working on some sort of side-scrolling Metroid game....(or not!)
Also, the wording does seem like they're implying that they haven't even started working on their next game; however I extremely doubt that they've done absolutely nothing for the past year and a half after DKCTF. I mean, if I were a development studio developing something for a console or device that hasn't even been revealed, the console developers won't be particularly happy about me spilling the info about a game that will exist on a future console that hasn't been announced yet.
And yeah, Wii U is dead, certain Nintendo fans need to accept this.
