Okay, let's see if we can look more clearly at possibilities - and that's all anyone has.
There are the nano-stands. A couple people have still gotten cracks. Is this a gating issue? Or better put, MUST it be a gating issue?
I don't think it must be. There are various options. First, the change could be successfully done before more serious issues are finished. But what if it isn't? Well, they could opt to ship with the latest version, knowing some percentage will have an issue - just guarantee that, if they crack, they can get a replacement. For that matter, just automatically send replacements when ready to all who ordered them.
Against that would be the question of cost. The cost of making more of a kind they know they will replace and the cost of shipping - which can be high for some overseas shipments. In any case, I see a real possibility that this wouldn't be a gating issue.
The ink coating for the green layer symbols needs changing because they fade. This is a bit more difficult. While I've seen fading on every keyboard I've had, this green layer issue does need to last longer.
They could ship as is, but I can see not wanting to - and not wanting to replace all the keys later plus the problem of the user having to change them out! So, maybe more of a gating issue, if not for sure. But if they are satisfied with the key design (and so far they have said so), then they may well have a lot of parts already made. Or they can make them fast (they've said they can turn out thousands of complete sets a day. Not super precise, but still could be a non-issue once everything else is ready.
Then we have the connections issue and "la-la" status issue. Which may or may not be related.
Which certainly seem to be definite gating issues. Well, at least the connections are. Not sure if the other is common enough to be gating related or not.
So, for me anyway, this is the area where all my attention is focused as far as progress is concerned and keep hoping new firmware releases solve it or at least improve it enough that it won't stop shipment.
From what I've read about bluetooth, it is a problem. Not hard to find reports of devices that use bluetooth losing connections. This is apparently a much bigger issue with BT low energy.
Is WT trying to solve something to get it to a level no other company does? Can it be done? If it can't be done, does WT decide that, while it was worth it to delay shipping when they felt they might be able to solve it, it isn't worth delaying if there isn't a solution that will be "good enough"?
I would hope, if it can't improve enough, it gets shipped anyway, but I really don't know if the average customer, if unfortunate enough to experience the problem, will like that. Not many of those are on the forums to ask. But it is a very important factor WT has to consider that no one here does. We only have to think about a decision that satisfies ourselves, because it has no effect on our overall businesses.
