Guarnteed successes and games I'm buying:

MGS4, GTA4, LBP

Maybe :
Resistance 2

Likely:

KZ2, Haze,

Haze - Possible flop - The constant delays may have turned some of the people anticipating the game off. Also the game is being released between GTAIV and MGS4, so people might ignore this game. It could go either way.

Metal Gear Solid 4 - Not - One of the most anticipated games and it's Metal Gear Solid

LittleBigPlanet - Flop - It will not appeal to the majority of the PS3 owners.

Killzone 2 - Flop - Unproven developers, huge bugdet being spent on this game.

Resistance 2 - Not - The first one did well, and I expect the second one to do better.

Grand Theft Auto IV - Not - It's GTA.

Haze = you got the wrong description, but I think it will do averagely
MGS 4 = not really, but yes in the eyes of fanboys (only 5m copies)
LBP = no, this will be masively advertised, and will do very well
Killzone 2 = no, the hype and avertising will be enough even if it is not so well received
Resistance 2 = this will be a major hit, great first game, even better second, this will be the new CoD
GTA IV = are you joking

MS 2 should be added, and I say no flop to that, it will sell big again and do similar numbers to the original with no bundling

only flop i belive will be haze.........selling at 1.5m

 That doesn't even make any sense.

Anywho, I think all of them will be successful, except for Haze, which may suffer from a lack of hype. They better have some good commercials...

But really, if LittleBigPlanet doesn't do as well as expected, Sony can just do a PS3 bundle with the game just like Viva Pinata. As for Killzone 2, I haven't heard a single good reason why it will flop.

And the others are guaranteed successes. 

Haze: Flop? - Hard to label a game I don't think was ever expected to play with the big boys a flop, but it won't have sales like the others.
Little Big Planet: Flop - Be a fantastic game but I simply don't think it will appeal to the generally more techy/hardcore gaming base of the PS3
Killzone 2: FLOP - A game far overhyped, a carry over from the 'PS3 domination starts with...' days, will flop badly.
MGS4: Not - Will sell well, will be very good. Its MGS, what can I say?
Resistance 2: Not - Resistance has introduced a large number to the series, multiplayer sounds good, will not flop.
GTAIV: Hell no - Its GTA for gods sake! This is like asking whether halo was going to flop.

Haze = flop. Even if it is a good game, no one will ever know it. It's releasing between GTA and MGS4.
GTA = Hit. I think it will be a big system seller for the PS3.
MGS4 = Hit
Killzone 2 = This game will be a hit in terms of sales with a sub 90 gamerranking.
LBP = Critical success with limited sales. Should have good legs through word of mouth and user designed levels. Too much hype for this game.
Resistance 2 = Hit. Proven story, great developer.
Home = flop. Sony is gonna take it in the seat for this one. They should can this project.

The people saying Resistance 2 could be a possible flop must be insane! The 1st game has sold almost 3 million copies since launch, this one should do even better than that!

I agree with Munkeh111

I think you've made a mistake with your haze description
