I'm afraid to say this but you might be right. Since the N64, nintendo consoles has been in decline apart from Wii and we all know the reason behind this which will be very hard for nintendo to replicate again. If Wii U didn't do anything to change other people's mind, there is a high chance the decline will continue unless they bring something new to the table which is very unlikely.
You can also bet there won't be much third parties support because ps4/xbox one will still have a few years left and even if it get ports of those games, it will flop anyway and the cycle will continue.
