Looking at the render on TKC, some keys were removed from the base kit render shown in the OP. The R3 PgUp and R4 PgDn are gone. There's no R4 1U Ctrl or Alt for the bottom row anymore. The 1U R4 Code keys are gone. There are other deletions as well; that's just where I lost interest and stopped. Check the new kit render shown on TKC (not the one in this thread) carefully before ordering.
There was a big update at the top of the first post and in this thread saying the base kit had changed. The render wasn't available at the time. We were working up to the wire to get this ready and it happened to go up on TKC before it was updated here. TKC is in Michigan, I'm in London so we are in different time zones. Hopefully that explains why there was a lag before this thread was updated (we're not trying to mislead anyone!). I've put the new render there now.
Regarding the key changes, we responded to feedback and made changes accordingly. As with any key set GB, a balance has to be struck between compatibility and cost. Sorry if we got rid of specific caps that you want but the kit covers a multitude of layouts and hopefully some novelties or alternative caps can be used in their stead. There are R4 1u Start and Select and 4x R4 1u button novelty caps to replace the Ctrl Alt and Code keys you mentioned, for example. Lots of people requested novelties for the set so we added a load. I'm sorry that you've decided it's not for you, hopefully most people will still find the caps they want in this final kit.
