Oh, maybe you missed your email? I got a Kickstarter Update on 17th December with the following info on t-shirts:
Our monthly T-shirt update is here, and after almost half a year of searching, we have finally found a factory that meets our ridiculously high quality goals.
If you haven't done so yet, please log into your BackerKit account to choose your T-shirt size as soon as possible. For reference, here is the sizing chart:
If you ordered a T-shirt, either as part of your reward tier or as an add-on, please consult the above chart and make sure you're happy with your selection. We will lock down your order this coming Sunday.
If you pledged for any tier of $1,000 and up, you are entitled to one or more free T-shirts. Please log into your BackerKit account and make sure you have selected the style and size you want.
If you want to make changes to your selection, please log into your BackerKit account at https://dreamfall.backerkit.com
If you have any trouble changing your selection, please shoot us a message at email@example.com, and we will do our best to help you.
We are ready to begin production on the shirts, so as soon as backers have confirmed their sizes, we will start shipping them out. The shirts should arrive at some point in January.
So, you see there is a specific invitation to log into the Backer Kit and make sure size info is current and correct. And they "locked down" this order on the Sunday after the 17th, which was 22nd December. So one would expect either to receive this order or to be informed as to what the hold up is. I doubt a separate invitation for re-confirmation of the shipping address will be or needs to be forthcoming.
I was just expecting some people to have got theirs by now, thassall.
