Not currently able to report on any of those things, sorry!

The RGB portion is the hardest aspect of the project to design. To do RGB the way we did involves using a many recently released chips, a new keyboard configurator, and we had to very carefully select our doubleshot PBT keycaps to ensure that they would display their characters properly. We also had to test every available mechanical switch variant to find out which ones had the sweet spot of being a consistent and high-quality switch with the weighting and feedback we consider optimal, while also providing excellent light-piping so that the legends are visible even under bright lighting. The frame is an open, floating design, entirely made from very reflective aluminum specifically to maximize light output from the LEDs.
That said, we didn't simply "throw RGB in as a gamer feature". There was a lot of discussion around whether or not we wanted to do RGB in a crowded market, and we only decided to do so if it was going to be better than the other implementations, while maintaining a professional aesthetic. We think that this is the most effort and thought that any community team has ever put into an RGB keyboard (HaaTa has been working on RGB support in KLL since 2014), and we are reasonably certain that after we have fulfilled our first shipment of the K-Type, we will see many keyboard manufacturers around the world implement our techniques in their keyboards. We partly did this to push the industry as a whole forward, and partly so that people could have access to a "best-in-class" RGB mechanical keyboard without having to settle for what the current marketplace has to offer.
You’re definitely right that we need to mention the hot swap more (though I know the reviewers will), so I’ll be sure to include that on our pages.
@JDragon Any sort of aftermarket cases other than color alternates for the K-Type are definitely a ways out. The case design is very closely tied into the PCB design, with some things like dual Type C connectors requiring special considerations. We’ll be open sourcing the case as well after shipping of course, so anyone else will be free to make cases as well.
