Roku Ultra, streambar pro and Bluetooth headphones for United Kingdom

Hi, Can sometime tell me if and when the Roku Ultra and streambar pro will be available in the United Kingdom, I have an old Roku 3 and would like to upgrade to something similar but more up to date and the new voice remote looks good, but it does not seem to be available; did think about buying an American version but a few apps such as BBC and itv will not have the right coding and the power plug would also need an adaptor.

I also note that the Streambar has been very popular, but does not have a network port and the remote doesn’t have a headphone jack can you use a Bluetooth headset instead on this item and the Pro version is also unavailable are these product coming to our shores I do hope so.
