Butterscotch, welcome to GS!
Like you, I don't know what to hope for in regard to Miki. I like her very much, and I admire her as a skater. But it's always hard to predict how a skater will do after a season away from the ice. Well, we'll get to see for ourselves at the same time everyone else does. Japan is certainly flush with talent in singles skating! I'm just glad they so enjoy sharing it with the rest of us.
Like you, I think Takahashi's efforts this year show that he is getting stronger, and so I don't automatically assume that another Japanese skater will pass him by. If Hanyu's so splendid that he can exceed even Takahashi, then good for him. But to me so far he lacks the magic that Daisuke brings to the music. He's certainly exciting to watch, though. Wow, this is going to be a stupendous season.
