So I see, PS3 version of GRID is delayed one week.
The Xbox 360 version sold amazingly, I think that only Halo 3, PES 2008 and GTA IV had bigger debuts for this console.
For comparision Burnout Paradise (I think it's the biggest 360 racer this year) sold in its debut only 2.65k.
I also think that ioi may have underestimated 360 GRID sales in Italy 2 weeks ago (for all Others he gave it 43k) and PS3 sales last week (we don't know Italy' number yet but seeing 360 version at almost 18k I won't be surprised if PS3 version will be over 30k and ioi sales are at only 39k for that week).
