What I appreciate about Dayan's recent releases is that they have been deliberate. With cubes nowadays being quite similar, Dayan was clever in recognizing the need in the market for soft-feeling cubes (tengyun) and lightweight cubes that aren't $65 (guhung v4). Even the guhong v3 was an attempt at appealing to the cubers who desired a smaller cube that is decent. This is much better than their previous releases like the zhanchi 2018 that didn't appeal to anyone. I'm optimistic about the new megaminx too because the megaminx market is not too competitive.
If Dayan is able to produce a 4x4 tengyun of decent quality, I think it could be a success too. (I don't know much about 4x4 hardware so I'm just guessing based on what people want in a 3x3).
