Why would Nintendo make another Console after so many failed attempts?

One failed console doesn't equal "so many attempts".

3 out of 4 starts to be though.

Out of their last 4 consoles, Wii was the only successful one.

Their profits say otherwise. 

I would expect them to, considering the wildly successful Game Boy Advance followed by the even more successful DS were pretty much carrying the company. A company making profit as a whole does not mean the consoles they were selling were a success.
