High-quality Vocaloid song

It seems like very exciting events/progress are going to happen. So first of all there is the mysterious hidden technology "Vocaloid Listener", partly developed by Yamaha, that greatly enhances the quality of Miku song:

It's hard to believe that this is computer-synthesized voice. The technology is rumored to be taking real human voice, extract the parameters, and import to vocaloid editor. Then there is somebody, who posted his work earlier today, without using the mysterious technology:

It's totally tuned by hand and the quality is extremely high. There's also a sample vsq file in the webpage linked above in case somebody wants to see what it looks like. Yes, it looked feasible for human hand.

I can't wait to see what's going to happen next.
