Honestly as long as the 360/PS3 are $50-$100 cheaper than the Wii U, I don't see the Wii U outselling them for a while on a consistent basis.
Not only is the hardware cheaper, but there's a back catalog of hundreds of decent-to-great games you can get for $15-$30 at any Best Buy, Wal-Mart, etc.
MS/Sony don't need to do much of anything really, just make sure their pricing is below the Wii U and they'll probably continue to outsell it for a while.
