Because, the 3DS came back with big support of both Nintendo and 3rd parties, along with a very nice price cut.
As far as we have seen, Nintendo is not making any money on the WiiU so a price cut that big would hurt very much. Many a 3rd parties are flat out not making games for the system. So that basically leaves them with first party Nintendo titles, which yes, they have arguably the best games, and by far the best selling games. However, I don't think the WiiU has anything in its bag of tricks to make the experiences new.
In the case of the Vita, it has one last hope in the PS4. It is in the same situation as the U in it is getting no software support.
For both of them though, E3 is just around the corner.
Stop hate, let others live the life they were given. Everyone has their problems, and no one should have to feel ashamed for the way they were born. Be proud of who you are, encourage others to be proud of themselves. Learn, research, absorb everything around you. Nothing is meaningless, a purpose is placed on everything no matter how you perceive it. Discover how to love, and share that love with everything that you encounter. Help make existence a beautiful thing.
