Because Miku was the one they focused on to enter America with. Miku being their company Vocaloid mascot was used to put her name out before her vocal was released. They tried, basically, to "sell" Miku to the audience

Though Luka has English, she is still aimed at the Japanese market, ditto its the same with Kaito and Meiko English.

Miku is their most successful vocal and will always be CFM's focus, regardless. Also, to include more characters increases licensing to use said characters, so by focusing on Miku you cheapen the production costs. Also, another point, selling several vocals at once can be overload to the audience watching, thus its easier to sell a single name ("Hatsune Miku") then several at once.
