I don't really see enough similarities to the Weilong to deem this a "v3". I'm a little surprised that's how it's being advertised. Those are big shoes to fill.
In contrast to the Dianma, instead of the edges being thinner than the corners, the edges seem a tad WIDER than the corners. Or maybe that's just the angle of the picture?
And yes, the corners do resemble a Zhanchi, but only around the base. The stalks actually remind me of a Lunhui quite a bit. Just with that middle anti-pop ridge being a bit rounder.
Overall I don't see anything that makes me think this will perform any better than the Weilong. I do love buying new 3x3's though
