Hi,
I have personally went down to the agent and try on the device, it's cool and the staff there provide good service. The 1st patch of the stock have sold out and I'm waiting for the new stock to come in, going to get one.
Have check with the agent regarding your question.
1) It does come in the 30Gb version too.
I am sorry VP8350 goes with 20GB only no 30GB HDD at the moment
2) Does the pic viewer support the RAW format of the D200?
VP8350 don't support the D200 at the moment. However, if you are willing to send the file for D200 for their engineer's reference, they will try to support it in future firmware version.
3) Can the batt be replaced? As stated that it can be charged approx. 500 times.
What happens once the batt dies?
Basically, all the batteries have the same situation. They do offer the spare battery if customers need it. You of course can replace a new one when the battery is dead.
4) Lastly, what is the transfer rate of 1Gb from CFII card?
According to their engineer, the transfer rate of 1G SanDisk CF ex.lll is around 2.6~3.2 minutes. Besides, the transfer rate is subject to the brand, type, files and environment etc.
Hope the answer is useful to you.
Regards
