Woah there, OP. Calm down, breath, and relax.
First of all, if you like your Wii U, the PS4 outselling it isn't suddenly going to make it less appealing. At least, if you are of a clear mind, it shouldn't.
Of course, I don't honestly think Nintendo can turn the system around at this point, for whatever reasons, but they are kind of stuck supporting it for the next couple of years at least in spite of that. I agree that a shake up in the company is needed, and I truly believe that one is imminent, so I wouldn't stress over the "poor leadership" as much as the OP is. Lessons are being learned, both from those in control, and those in control of those in control here, so change will come naturally in time.
For now, though, Wii U releases may be sparse, but Nintendo still has some good stuff on the way to look forward to. I say enjoy it as best you can, and get a second console or a gaming PC if that isn't enough for you.
