I really wouldn't worry about GT5 just yet.
Its a franchise that has a lot of casual appeal, we could see lots of on the day sales for the game, also this is a legsy game. Last but not least its Black Friday week!!
We have full GT4 sales data so we will be able to keep a full track of how GT5 will be doing
GT4 Week 1 in NA was around 770K.....if GT5 gets within 200K of that we can hope for it to make up the defecit as GT5 is on a younger console not at mass market price.
