GoCoin says it includes Regal Cinemas which are owned by the US Regal Entertainment Group. However, there is also a UK theater chain called Regal Cinemas. Sadly it's not connected to the US company, but they might notice the news and follow suit because the US company has exactly the same name.
Yeah we can hope so, this kind of news can only be positive. Companies/organisations seem to follow the trend so if this is a success another movie theatre company/chain may follow suit & then another etc.
Mainstream adoption is going to take years & years but I have time to wait
