The language is only half the problem... A lot of languages are already recorded and all they have to do is map the sounds out and make the recording script. Developing the vocals is always much harder and takes months sometimes to do, depending on the language you'll be looking at a year and a half at times.

New languages are always the most problematic to launch. Out of Chinese, Spanish and Korean the only one doing well is Chinese. Korean is struggling and Spanish is basically dead. The reputation of the Japanese vocaloids can be overstated and often people buy them thinking they can either handle them or their "cool" and find out they can't. Bilingual Japanese/English are becoming more popular among western producers for this reason and they can fall back onto English if worst comes to worst.
