To be fair they weren't personal expectations; they set dates, missed them by a mile, and still don't have dates available.
To be close enough to be giving a date of early January from the day of announcement, to suddenly not having any dates at all in early February is a giant fumble from them and there's no way around it.
Labeling it as "personal expectations" is just false as they set the dates that everyone was expecting. With that said at this point we just need to be patient and cancel if it gets too much for anyone. Badgering for dates here won't make it come any faster and we just need to accept it at this point.
I will say, I think you are focusing on the wrong aspect from their message. I don't believe they are specifically looking for the adapter pictures, they are bringing up that even now a month after their initial release period we have seen very little of the actual headset.
