Here's the last few paragraphs of the article:
"Official pricing and availability for the Samsung Gear S3 hasn’t been announced yet. The Gear S2 cost $300 and $350, therefore, it is very likely that Samsung will price the Gear S3 along the same lines. It could be more though, we’re not sure.
As for the release date, the Gear S3 should be available for purchase by the end of October or early November.
In Europe, the Samsung Gear S3 will start at around €399, which is around $300 considering the difference in currencies."
I can't figure where the website (News for Blackberry & Beyond) is domiciled, to know what they're using for the currency conversion. But if they're in the USA, a Euro 399 price does NOT equate to a US$300 price - it's around US$447 at current exchange rates.
