Get one while you can, cause this is gonna land with a big thud.
The big PITA with the VG series is that Sony - in its endless crippling of its camera lines to protect pro cameras - has once again left the customizable picture profiles off the VG30/900, leaving you with very limited video image options. You're stuck with a look that Sony has decided you should use.
The VG line is trapped in the consumer camcorder realm - which is laughable as no casual video shooter is going to buy a $3300 FF camcorder and monkey with that goofy adapter and expensive Alpha lenses. The DSLR cinema shooters want more control over the image and will continue to use 5d's and likely the A99. For stills its no biggie if you're shooting raw because you're not using the portrait or sunset settings, but in video these are crucial as that's the only way to adjust in-camera sharpening, contrast and saturation -- something I can do on the $300 second hand Nex5n I use as a backup camera. Go figure.
A lot of VG20 owners got burned by Sony showing the profiles in the initial spec sheet and then never seeing them on the camera. IMHO the appeal of both the VG cameras is very limited until Sony unlocks some control over the image, something you can do on all the Nex and Alpha cameras. I'm personally considering the A99 as a second camera over the VG's for that very reason, despite a form factor on the VG that's perfect for shooting video.
The VG900 feels more like a "we built it, because we can" camera, rather than meeting what VG customers have been screaming about for a year. If I'm stuck with Cinematone and crap like toy camera and sepia while shooting video - pass. Maybe the RX1 developers will do a video camera - FF with a permanent Zeiss zoom.
