According to a news post on Vocaloid Otaku ...:
"The CEO of Crypton Future Media announced today at his New York Comicon/Anime Festival panel that there will be an English Miku if her facebook gets 39,390 likes."
Might just be an English-language release of Vocaloid2 with the Miku voice samples (which would be very nice indeed) or it could mean they have a set of English-language voice samples with Miku's VA. Probably the former.
Nevertheless: if you'd like to "vote", go to http://on.fb.me/cB1xga and "like" it.
das ist allus.
