I'm in for one but I live in California so I bought it off B&H Photo instead. They don't charge tax to California residents like Amazon does. So I saved about $9, plus free shipping.
I've played this on PC and enjoyed it. It also got me to watch the TV series of the same name, which imo wasn't half-bad either. Thanks for the heads-up on the free PSN version!
I really do hope they offer an online upgrade much like they had with a few early PS4 titles. I'm willing to pay at most another $10 to play over again on the PS4.
I'm guessing it took long for COD to ship because of the demand and low price. It was probably backordered after the first rush of orders were fulfilled and the rest of us had to wait for new stock to arrive.
I bought this on Groupon back in mid Nov. when it was $35 w/ code. It's just shipping now. Great deal but don't expect it to reach your home anytime soon.
