Actually the problem with GAN is that it doesn't like to step in the global market of Puzzles except the NxN puzzles. Look at its history. It has a lot of puzzles and their updated versions. The 460 M 4x4 is available in both stickerless and stickered. It then came out with two versions of the 249 M, both having stickered and stickerless types of their own. The 356 line has so many more versions including the X, XS, R, SM, Air SM, i, XM, Air UM, RS and the 330. Recently it also came out with the MonsterGo collection for beginners including the MonsterGo Cloud Blue and Pink. And finally the latest GAN Megaminx, unfortunately, only in stickerless. These variants, considering both their stickered and stickerless types, amounts for some 30 types of cubes!
.
Now this is the problem with it. It is continuously improving the mechanisms and types of the 3x3 only. Sometimes it changes the magnet replacement system, and sometimes, it switches to a full plastic core to make the cube light. It isn't ready to come out with other WCA events. I mean, just think about it. A GAN Pyraminx? With some 60 or something magnets? A GAN Skewb? With 60 magnets? A GAN Square-1, with 64 magnets? These will hit out the market just as they'll come. GAN is known for its premium products and this one will really help raising its popularity among other speedcube manufacturers
.
I personally feel the need to have more types of puzzles for their respective events, rather than having the same event with many types of puzzles. Why didn't I replace my Rubik's brand 3x3 with some flagship speedcube 6 months ago? (It performs really good though now!) The reason simply being that I wanted more events rather than some new 3x3s. Instead of getting the new MGC Elite right away, I first went on for a new Megaminx, Pyraminx, Skewb and a 2x2.
.
Now I have 5 different puzzles instead of having the same old 3x3. This really helps a lot to keep a balance between all the WCA events and keeps you ready for all WCA events whenever they come.
.
So personally I feel that GAN needs to produce "new types of products" rather than "new products". It would be really great if it can make all WCA puzzles at the earliest. Being a Sub-5 Pyraminxer, I really look forward to a GAN Pyraminx. With 36 magnets or so, factory default blue GES nuts, lubed with the Angstrom Gravitas Angstrom Dignitas and the DNM 37 or Lubicle Black or SCS Cosmic Nebula, and stickered with the best quality stickers or maybe stickerless. I've used only one GAN product till now which is the 356 X and I actually love the feel of GAN Cubes! I mean, its not super impressive, as I have some preference for the MGC line and the Kylin Black line of cubes, but the texture, the turning and the smoothness makes it feel like a premium product actually!

Not a big fan of GAN cubes, but will surely join the GAN fray if it comes out with puzzles other than the NxNs and the Megaminx!
