I can see Charles keeping on Birkhall for him and Cams to use - otherwise they would have to visit Scotland less often as they head up a lot now without needing to open up "the big house". Maybe they'll let W&C have the sovereigns rooms in Balmoral for when they visit in the summer along with the rest of the RF. Without being too morbid C&C are getting on - moving out off Birkhall, moving W&K in (As I assume they would do) and moving C&C into Balmoral only to then eventually move W&K in when William takes the throne may be seen as a bit much. Or of course they may keep Birkhall for all but the "summer hols" or maybe they'll ditch it all together.
Personally I think Highgrove will be opened up more so people can enjoy the gardens with maybe the odd visit by Charles. He seems happy to use the Castle of Mey and Dumfries in that way.
