Like some others have said its WAY too early to tell considering MS and Sony have unveiled litteraly ZERO of what their new consoles will be like and even Nintendo barely showed us anything.
In other words there is no way of knowing cause we don't know what the competition will bring to each other and where the game software is going to go.
That being said I do think Sony and MS are currently in a better position than Nintendo and I personally don't see Wii U being near the seller that Wii was. I think it will be successful and profitable but not like Wii has been.
But I could be horribly wrong and thats part of the fun of predicing this far out of launch
