It's a strong possibility for sure.
Also the game is still #1 and the Deluxe Edition is #2, usually at this time and into the US it was #3 most of the time, but I guess that CS2's newest update revenue is slowing down.
Game just keeps on selling(#1 and #2 in
CA/
US).
This being very US/NA centric means that the average sales price on Steam is likely much higher than most releases which can have sometime have a very large amount of copies sold from countries where the regional pricing just makes them worth much less in USD. The game is making bank, even with the reduced price point.
