Yeah I've noticed this over the past few weeks actually.
Like I said before, the Wii U can turn it around with a steady stream of brilliant titles. It's the games that make the system and hopefully SM3DW's critical acclaim will convert into commercial success.
The last few major Wii U titles all signal the start of a turnaround. We already know some of the big games coming next year for the Wii U, and all it needs now is some more good titles filling in the gaps between those upcoming major releases.
