It is a shame that they seem to be skipping the 14x14, I understand that 14x14s are a bit harder to design but it would be nice if they genuinely went in order with magnetic big cubes as right now the only 14x14s available are from ShengShou and more recently, YuXin.

DianSheng have released magnetic big cubes under their Galaxy series from 8x8 up to 13x13, all these cubes are available here at speedcubing.org and I might stock the 15x15 too, I just hope they won't jump the price up too much. The puzzles all turn brilliantly so far so I highly doubt the 15x15 will be a major downgrade in performance.

AP has uploaded a video unboxing the puzzle and it seems to turn very well, I very much expect we will see him breaking his own unofficial world record for the 15x15 in the next few days.
