One of the few things that sounded like truth in the recent messages from BrainMacKenzie was that he didn't know how to render the action in the basketball game and was trying to rework that. Trying to show action in a game with few animations can be tricky, so that little nugget stuck out as being possibly true.
The last time there was a mental logjam like this was the much delayed "Pool Party" release, which also went through a similar timeline of delays and excuses. Trying to do water scenes (in a pool or the ocean) is a challenge in Daz. Some artists do a great job, others struggle and looks pretty bad (like WMV's purple pool water).
I'm more inclined to think there just hasn't been any substantial render production for a while, and the latest drama is another delaying tactic. When the pressure gets more real (through lower Patreon subs or a pending Abandoned tag), we'll probably see a release of several hundred renders.
