I will say when I got my PS4 yesterday I was tempted to ebay it, easy $200 profit.
They're selling for ~$560 right now on ebay. Subtract 13% (ebay + paypal fees), and then subtract $400, and you're left with $87 (less if you paid tax on your ps4)
They were selling for $650-$700 at launch, so the price is only going down (sold my ps4 for $650 and xbone for $845 at launch).
