I also doubt all those magnets are really helpful in any meaningful way, and they are likely there mainly to sell more cubes or to justify higher prices. We will find out in time, whether the extra magnets in the feet of corner pieces, inside the centre caps and elsewhere are worth it. One thing that is increasingly clear is that Maglev has negligible advantage in performance, based on many really top performing cubes with Springs that are as good or even better rated than the Maglev versions, eg the Tornado V3 Flagship, Picube Weilong V9 SE, etc, and recently the V100 Leap. There have been so many cases when the top version with all the extras magnets are not doing any better than a model with less magnets.
I'm afraid that the added weight from all the extra magnets almost have to have compromises in other areas. For example, the maker has to reduce weight, like using lighter plastic or thinner plastic, thus making the cube feel hollower, the pieces having less inertia (not good for turning), less solid, less rigid. I can understand how adding and mentioning all those extra magnets or their numbers can look impressive and create sales easier, more so than harder real work and ideas that IMO can make real differences, eg to redistribute weight (towards the centre of cube?) or to construction to make the ball core and axles more rigid (one-piece moulded design?), fine balancing of weight of cube pieces and the moment of inertia to make turning more stable, less catchy and controllable (similar to wheel balancing on a car) etc.
