That’s not accurate. The last expansion released in July and, according to steam charts, the game received a 79% gain in peak players relative to the #s before the expansion when it released.
Each month since then it’s been about a ~25% decline, which is the same rough monthly percentage decline you see in other CCGs like Faeria between expansion releases.
Also, these are just the steam numbers. Is this 1 to 1 with the Windows client? Who knows.
If I were involved in the business of Duelyst and it was my decision to focus on more frequent content updates vs. new platform releases at the expense of new content for a while, I would push to get on new platforms first and then try to get back to more frequent content updates.
That said, I would also be transparent about that choice to the community so they weren’t left in the dark.
