4-packs sound great except that most of us will only ever need half of the keycaps in them. I'd want to pair up with someone who needs 1.25u and 1.75u but not 2.25u and 2.75u so that both of us gets only what we need and aren't stuck with keycaps we don't.
As for the Dolch 2.75u experiment, you're right I don't have them yet. For all we know Melissa's definition of "worked" is different from ours and we'll all be disappointed (none more than me who paid handomely for the experiment). But I remain hopeful. We'll know soon.
Yes, I agree with you. They should sell ANSI as a pair (since almost all sets have an ANSI base kit even for those who have ISO kits and for resaile purposes it's best to have a full ANSI base), with the others being available as single caps. They have the original GB numbers so they could make matching numbers for these (actually probably good to make a few LESS than the totals due to some people not knowing about them which is inevitable unless emails go out to every buyer, and even then some will not bother to purchase them).
And just to clarify, these will not go through the PMK group buy system. They will not need an IC voting phase. They'll get made and then become available in the PMK store directly.
One thing I feel should be mentioned here. It seems SP is actually starting to pay proper attention to the community (when we can demonstrate concensus on a subject), even though they are not very active in the forums. If there is a real issue we want to address with them, it's best to have a discussion between stakeholders in that issue, reach some kind of concensus and then have a single contact person present it to SP. That's how we managed to get this done. I see a lot of complaining about various SP related issues and some people may even have sent an email to them about the issue, but SP has no visibilty of the community concensus. It's no good expecting them to know general feelings of the community through all the different threads we read here. It simply comes across as individuals whining, which it sometimes is. So if we want to get things done, we need to present a united front.
As a PMK/ SP sceptic with a bit of an "us vs them" attitude I can say that things do seem to be changing.. I'll post more about this in their subforum. I actually have hope now that the new PMK system could work, eventually.
