Just around the time that I put the new AoSu V7 up for pre-order, MoYu begin the teasing process for another interesting cube. It is often the case that the 5x5s are released before the 4x4s as 4x4s are essentially 5x5s with invisible inner pieces, I suspect MoYu just decided this time that they wanted to release the 4x4 first even though they already had a good 5x5 design. I currently use the PiCube core magnetic AoChuang WRM but it seems that the original AoChaung WRM is now permanently out of stock, I suspect MoYu will be able to improve on the original design and provide the puzzle with core magnets in the factory, so I am very confident that I will be using this new cube as my main pretty much as soon as it comes out.
Luke Garrett (who is sponsored by MoYu) received a sample of it and got a new PB single, it says in his video description that it was a 'dual track magnetic cloth version', I suspect this is MoYu speak for UV coated and ball core, however, it does suggest that MoYu may try and release a few different versions for this cube as well!
