Why is the A1 Combo shipping delayed when components are in stock?

So I ordered my A1 Combo on 1/13 and the order page showed an ETD of around Feb. 10th; I'm fine with that. But, when I go to the site now, I see an ETD for the combo of Feb 14th, but both the A1 printer and the AMS Lite are in stock to ship now. I don't understand
