I actually preordered this item at Best Buy as a store pick up item. Only to find out, the item ended up being unavailable, no Best Buy stores have any, and it is out of stock for ordering now as well. My order with them is currently hanging in limbo pending details on when they will get more, if they will get more.
So I started looking around, at a lot of major retailers, such as walmart, kmart, target, etc. None of the retailers have them in any stores in my area, and none of them have them in stock to order online. Even the Microsoft store linked on the xbox product page for the adapter lists it as being out of stock.
Did Microsoft really fail to prepare enough of these for the products launch, or was there some sort of major breakdown on the supply of these to retailers? I'm kind of frustrated about it, as the cheap xbox headset that came with the console is actually quite painful for me to wear, and Titanfalls release is tomorrow. I really don't have the money to fork out on yet another expensive headset, when I have a few other good ones laying around, that I just need this adapter to use.
