nothing lol

Touche.

MGS4 could have a drop when MGS Rising appears

Yup, that's pretty much what I'm saying. I think FF XIII will be out first, but we'll see. There's still no release date for GT5 yet and it's been in development for over 3 years.

If anything it would increase sales since it would probably reinvigorate interest in the series.  It isn't like it will be Madden 2010 or Modern Warfare 2 that makes the previous game mostly obselete. 

this gen? MGS4, GT5, MW2, FF13 and maybe FF Versus 13.

final fantasy 8 remake!!! :D

GT5 or MW2...whichever comes out first

Here's my picks with previous sales in brackets

Guaranteed:

1. Modern Warfare 2 (MW - 4.29 million/ WaW - 3.28 million)

2. Gran Turismo 5 (GT5:P - 3.05 million)

3. Next Grand Theft Auto (GTA4 - 5.63 million)


Possibly:

1. Assassin's Creed 2 (AC - 3.38 million)

2. Next Metal Gear Solid (MGS4 - 4.04 million)

3. Final Fantasy 13


Highly Unlikely

1. Uncharted 2 (Uncharted - 2.44 million)

2. God of War 3

GT5 and Final Fantasy for sure...I also think MW2 will easily do it...remember that COD4 was released in 07 when not many ppl had a ps3, now that it's 2009, the ps3's install base has increased significantly...i also think metal gear rising has a shot but it depends on the gameplay...if the game is hack n slash then no, but if it returns to the traditional formula then yes...lets see what else...i think if they release a killzone 3 and bundle it with the ps3 it will sell like hot cakes...but yeah, that's about it
