Hi paulcymru,
It looks like VM will send new voice remotes if the current V6 is upgraded, but nothing has been confirmed yet about regrades/updates.
The following info is from VM Staff BenMcr
There are two things that have happened recently
The first customer pilot replaced any existing TV kit with the new customer experience which is 1 main HDD box and any additional boxes are the 360 mini boxes.
There is now another customer pilot. That is where some existing customers with V6 boxes are being offered an upgrade where the boxes are converted to 360.
Both of these are invite only.
As yet there hasn't been confirmation as to which option will be available for existing customers for the 360 when it becomes a normal upgrade that you can ask for.
