Megpoid Native will be an updated version of the Vocaloid 2 version of Megpoid, having some improvements and fixing some problems. She will be released on March 3rd, 2012. Anyone who pre-orders her will receive a technique guide. Just like Vocaloid 3 Megpoid, she will not require the original Megpoid. She will run on the Vocaloid 3 engine. As stated in one of the demo videos:
Fragments Of Star
Sounds cool enough, maybe I'll ask for her for my birthday... There should be a bundle with her and the V3 editor (there probably will be, idk). She sounds A LOT better then her V2.
