Hiding deep in my RSS aggregator was this little gem:

Essentially, according to an interview in DTM Magazine (01/2009), the newest addition to the Vocaloid line will be bilingual! Yes, it will pull from both an English and Japanese database for it's words making it accessible to both Western and Eastern audiences! Other details include updates to the interface for English use, such as native English input, katakana input, and dual DBs in a single track. [needs verification]

Anyway, time to trowl Japanese book stores until I find a copy of that magazine. Spend Spend Spend!

Edit: Whoops, forgot to cite the Source

Yes, you heard right. Rin just got a new twin brother: Kagamine Ren (鏡音レン). Both of them will be "voiced" by Shimoda Asami, exactly as declared before.

Ren has the following descriptors:
• 14 years old
• Height: 156cm
• 47kg

and he excels at:
• Dance & Rock Style Pop/Pop Songs ~ Enka Style Pop
• Song Tempos: 70~160BPM
• Ranges: D3～C#5

It seems like Rin was also slightly updated. She is now also good at Electo Style Pop music.

Seems like Ren has a slightly lower range than Rin does (obviously), and enjoys the frilly boy style of music made popular by kid boy bands. Nonetheless, I'm looking forward to when Crypton finally releases demo songs for their new characters. New boxart and big image after the break.
