I had a few Mask sets as a kid, not as many as Joes but I enjoyed the transformation features more than Transformers and the toys were exceptionally well designed. I was just a bit disappointed by the scale back then, had they been the same scale as my Joes, I would've done anything to have them all.
The only experience I have with The Loyal Subjects are their blind boxed Aliens and GI Joe character figures; nice figures that fall apart easily and were too expensive for blind boxes. I've heard their BST AXN figures have poor sculpts, paint, and can have loose joints that fall apart. I never bought one but I hope they've learned a lot since then. I don't have much faith in them making some very complex toys like MASK vehicles. They at least have a few improved features in their teaser images with blast effects and better articulated figures (the figures look like they have ball jointed shoulders). I hope these are scaled a little larger to GI Joe 25th Anniversary figures and vehicles or at least, to the classic 1:18 scale GI Joes but, widespread rumors are that these will scale with the original MASK line (2.5" tall figures)
Too bad Ramen Toys was skipped over, they do make some nice stuff no one else wants to... Good news is that my Ramen Recoil Van just shipped today!
