Not only it can as it most probably will, at least for the next 2-3 years. Its likely the Wii U will be the highest sold next-gen console.
After those 2-3 years the price of the other consoles will become more acessable and they will catch up.
I would advise "would be" analysts to think about price points and game availability in the future and not jut what their own needs are at this moment.
