It looks like Motorola is going to grow its ZN-series phone. With the recent leaked on the ZN5 candy bar phone, ZN200 can be read from the Motorola phone profile page.

No photo or details is available now, but judging from its 176 x 220 resolution display screen, it should be a mid to low end phone with keypad.
[13-June] Update: FCC have published the phone pictures and user manual
