Feel free to add links where PS4 or Xbox One´s are still in stock, so we can have more understanding of the stock situation. Besides this way we can help those who are still looking for one!

Yeah, Walmart got a huge shipment for sale on Sunday.  So much for being supply constrained.

Links....

Not everyone buys at Gamestop!

Besides i doubt these places will be able to satiate the demand of 2.2 million costumers!

The PS4 links are Sold Out.

Go to walmart.com and search for stores near you.  Everyone near me had them in stock.  It has dwindled a bit, but still, at least 2-3 stores in a 20 mile radius of me have stock as of 2 hours ago.  I snagged a ps4 using the walmart right by my house.  Walked in around 9-10 (don't remember exactly).  They were made available 8 AM Sunday.

I think Target had some too though much less.

PS4 has been harder to find than Xbox One though.

-----

Just checked again now.  4 stores within a 30 mile radius have them.  In store only, but you can search for stock using walmart.com

I don't know about Xbone but all the links the OP shows PS4 Sold Out.

And 2.2m was about PS4 only.

Both are waiting lists.

A large chunk of that on either console could be flippers (which has all but collapsed). Another large chunk could be people who found the console elsewhere in the meantime and will never collect from Gamestop.  Going into Q1, we'll have a better idea of where the numers might stabilize at, but until then, a lot of speculation.
