More fan backlash due to another hiatus probably isn’t preferable. Also, I’m sure they have the math down on profitability when it comes to how they schedule their releases. Releasing every two or three months might be better for sales than rushing through all of the content and then having to go on hiatus.
But all of this is just speculation. Who knows what they’ll do or why they’ll do it.
You're right, I'm sure they have the math better on when would be the best time to release. The wait continues, hopefully s10 v1 starts shipping soon.
