How will the PS3 do in 2008 when its "big guns" (GT5, MGS, etc.) come out?

I can see GT 5 really helping out the ps3. I know a lot of people who are waiting for that game to come out before they get their ps3. I think GTA4 and MGS4 will get pushed back till fall 08 since that is when people buy games in large numbers.
