I just want to let you know that I am back, and I really appreciate and take into account the feedback and comments you leave on this thread, so please continue doing so! The long time between updates just means that we have been working hard on sorting out legend specifications and funding in private; we may have news and/or renders for you soon, and we are as excited about things as (hopefully) you are. This set is pretty ambititious, combining polycarbonate keycaps, glossy ABS, and a new Eurostile like font (Check Oobly's posts and the OP for details, as he has been creating the legends and renders, and thanks to hashbaz for the Cherry legend SVGs), so development time will probably be longer, but hopefully we can create a keycap set that raises the bar for what can be done.
Also, I would like to ask for your opinion about making all modifier legends icons rather than text, as a possible backup plan to reduce legend costs if we cannot fund a whole keyboard. While we of course would like to have a new SA font available for every key, I want to know how happy you would be with the set if we did have to reuse Signature Plastics' icons on the modifier keys. Would the set become unusable for you? Would it make it significantly less appealing for set designers? Will it make "Classic Space" look less consistent, aesthetically? I'd like to know what you think.
If by any chance you are still in doubt, any issues with MiTo and Cospar have been resolved, and he has even created a banner image for "Classic Space" (Thanks!). Also, livingspeedbump's gifs are pretty cool.
