I sure hope Dark Link or Shadow Link makes a return this time around. I think the implementation of Wii Motion Plus could really make a very memorable battle.
As for those who think cel-shading would ruin his design... I have to say, "Are you kidding?" Cel-shading can really work wonders. For example, many anime titles have very, very dark and twisted scenes. What is anime colored with? Cel-shading. You've got to realize that "cel-shading" doesn't mean bright and happy colors. It means that flat colors are used, so you see the edges of base colors, shading, and highlighting colors against each other instead of blending in. Many of you kids into mainstream anime might have seen Death Note, a series using very creepy and sinister cel-shading. Some of you might have played Prince of Persia (not the new one) or Borderlands... those have cel-shading.
So, I think this is a chance to make him look more awesome, evil, and creepy than ever before. And, paired up with WMP, I think he could have potentially the best battle scene in a long, long time.
