I would be very suprised if the 8800 series, 8300 series, or 8200 series would get OS 5. It's a pretty demanding OS hardware wise. I have a feeling those devices with 4.7 will be the only ones to get the upgrade.
I wish there was a better way to search on these forums. The 5.0 OS will be on the 8330 because it has enough memory to run. It is the only 8300 series device to get it. The 8830 will not as it does not have enough memory to support 5.0.
