GTA IV is still #1, but for how long?

Looking at the game rank across the 1337pwn.com community, we've noticed an interesting trend during the past week or so. COD4 and Halo 3 are regaining ground lost to GTA IV.

1. GTA IV (1000)
2. Call of Duty 4 (957.7023940445)
3. Halo 3 (809.49158277641)

With folks completing or abandoning the single player campaign, how long will GTA IV remain at the top?
