Just keep in mind if you're waiting for a further discount at a B&M store chances are the ones left over at Best Buy or Gamestop will be in much much worse shape then what you'd get from Newegg.
If you're only buying it to gut or don't care about the condition of the outer box then chances are best buy will eventually hit $59.99 but I don't see Newegg going much lower if it drops from this price at all
All of these gigantic box CEs have a limitless price floor - over time, retailers will be practically giving these things away. And while the above statement is true for the in-store stock, when you order online, you get warehouse stock that's typically still in the original shipping box that they
received. When I bought the Arkham City CE from BB.com, it was this way. Agree with the CAG who pointed out that Amazon still has these in-stock online (and so does BB) - won't bite until less than $50.
