From what we know, they rendered it originally in Vocaloid 2, and had to re-render it in vocaloid 3. This means building up the vocal from scratch. Plus take into account their updating Miku's 7 Japanese vocals at the same time, taking them from vocaloid 2 to vocaloid 3. :-/

Between this and the number of vocals CFM are investing in, Luka Append, Meiko update, Kagamine English, the V2 -> V3 updates in general... Thats a lot of vocals and a LOT of work. Their progress is likely slow for this reason.
