A few people have asked this question (including myself where i have asked NOW on more than one occasion and never got an answer).
As normal NOW keeps things close to their chest and never divulge anything until something is 100% certain.
You are better off looking elsewhere for a NOW Stick unless you are waiting for a replacement under warranty from NOW.
if it was me i would seriously consider an Amazon Fire Stick over the NOW Stick.
I have got my own theory on why NOW haven't stocked the NOW Stick on their website since around October 2020, but keeping my speculation to myself until something more materialise from NOW themselves.
When i checked the other day NOW are not even advertising the Stick on their website shop anymore, where previously it was showing the Stick out of stock.
Don't want to speculate anything until NOW officially come forward with the reason why the Stick is removed from their website shop (even though it's been out of Stock since around October 2020).
As things stand if it was my money i would splash it out on a Fire Stick than trying to find a NOW Stick from other Retailers (unless there is a feature such has live pause TV that appeals to somebody using the NOW Stick).
