I think Forza & Microsoft have taken too much of GT & Sony's market away for GT5 to challenge Halo 3's lifetime sales.
I also think the fact that GT5:Prologue has been out so long and is getting DLC will mean that many owners won't feel the need to pay another $50 for an expanded game.
Personally I'd be surprised if GT5 even outsells GT4
Never argue with idiots
They bring you down to their level and then beat you with experience
