Even though that screen is similar in nature to the ones we used at the store, I have to say that for now I believe it is fake.
I, a Gamestop employee (EBGames and GS used the exact same POS system), notice some incongruencies with that screenshot provided.
1. First off, the reserve list is not in all capital letters.
2. Some abbreviations are never used (like STN for Station).
3. We use the full title on Super Smash Bros. Brawl.
4. The "
WII" at the end of each title is not there at all. It is replaced by the SKU after the title.
5. All confirmed online titles have "OLC" infront of them.
7. Street dated titles contain after the title "(sd: DD/MM)
Of course, this is based on a US store, I will check for you guys tomorrow and provide feedback on this.
