We are planning an update to the F28 that will be in the same order of magnitude as our recent 146 version 2 update that will bring the 146s feature set across to the F28, including the UNS-1 FMS, as well as a few extra features. We aren't able to give an exact timeframe for when this will be released, but we'll keep everyone posted on our social media platforms.
The 1000C/3000C is something we have always wanted to develop, but haven't been able to due to a lack of reference material. In the time since the F28's release, we have been able to source some limited reference material, so we can now judge the amount of work required. There is quite a significant amount of work required for the 1000C/3000C versus the passenger variants, for instance, it would require changes to the cockpit configuration, a brand new cabin with a cargo door, an updated flight model and additional sounds. It's not something we can commit to at this time, but if it's something we are able to develop in the future then it'll likely come in the form of an expansion to the F28.
