Most of the rest are 3rd party vocaloids that struck deals with Yamaha like Macne Nana's devs did. Yamaha doesn't make its own vocaloids normally (Kaito, Meiko, VY1 and VY2 are the few they have "made" as per say). Merli and Lapis are part of this group and due to their more success, I expect them to get a update and would be surprised if they did.

As of Internet co, I actually expect them to consider updating Cul and co at some point. I guess they won't move so fast though, due to them not being such a big hit as their V2's, and some being only about a year old (esp. Chika). I'd like Chika to get a second vocal, as Kokone, just to separate them more from Gumi, especially Chika. :-/
