Honestly, I don't know. Last couple of predictions I had for splinterlands and for hive were completely wrong so I don't do much thinking about future predictions.
As for Rising star, I really like how devs add new varieties all the time, like this whole year event of world tour and card blending, crafting. I can see it going for a long time. But I'm mostly idle on discord so I'm not so much familiar with actual announcements if there are any to consider.
Oh well i did hit the nail with the hive prediction, like my powerdown firts drop was just in time and all that shet, but beyong that splinterlands is a chaotic place, and rising star have these new cards each several months and omg i love the artwork of some of it, beyong that i like the halloween event idea, it was awesome :D
