I made most of my case for CFM's logic behind Miku English and many apply here to Miku V4. Miku is money... She is ranked as the single reason Vocaloid sales went up by 19.2% last year, thus we can attribute most of the % being for Miku V3 alone.

I think we can expect Miku V8... And they already have an idea for Miku chinese, so expect that at some point in the next two engine eras... *sigh* :-/
