Understandable, the article said that it's most likely just for South Korean (and probably Asian) market :
I did check with someone at Sega UK about it –
they stated that they do not know of any plans for this model to be headed out West,

In Asia, arcade centers has operated again since last semester.
And Arcade centers near my place has opened again too.
Not as crowded as before, but at least there are always visitors (mostly children now, not teenager as before).
They put many hand sanitizer every few meters and gave us plastic gloves too.
Gambling machines were prohibited here so I guess the situation's rather different than in Britain.
