The article above is an interview with an Assassin's Creed dev, and you can tell just how excited he is about the Wii U port. In fact, he sounds extremely excited.

 

But why would he be excited about a game on new hardware (that's supposed to usher in a new generation) when it looks exactly the same as the last gen hardware? It doesn't make any sense to me...
