I cant pretend to have any inside info, but I think she will be waiting a long time for that.
I dont think the Niagra will share the 9530's GSM support. I expect the future VZW line up to be:
Blackberry model: positioning
Apex: consumer flip
8830: non-camera legacy business model, international roaming with traditional keyboard (kept around like the 8700 series is today)
Niagra: Curve replacement, no gsm but the highest end keyboard BB.
9530: Highend, multimedia and world traveler BB.
For businesses Id expect VZW to push the 9530 for the flashy CEO types and the 8830 for the grunts who cant have nice things.
They arnt going to build gsm into everything.
