Gran Turismo 5 is the big one for me, it will sell lots of consoles and will be an amazing game, Tekken 6 should be good when it finally comes out, M.A.G has the potential to be HUGE as does LBP, infact i think LBP may be GOTY

Gran Turismo is by far the biggest, assuming it makes it out by the end of next year.

After that:

1. LittleBigPlanet
2. God of War III
3. Team ICO's project, but maybe Killzone 2, depending on how good it is (and we all know how damn well shooters sell).

Of course, this is assuming Uncharted 2 and Resistance 2 don't do much more for the console than their predecessors. Though Resistance 2 may be big, depending on how massive the improvements are over the original (and they seem to be doing a hell of a lot).

Oh, and FFXIII will be ginormous in Japan.

1. ff xiii
2. gran turismo 5
3. resistance2

I think you need to learn how to count...

Anyways, I will say the following three are the most important excusives: God of War III, LittleBigPlanet and inFamous.

Most important franchises/series

Old list.

1. GTA
2. GT
3. Final Fantasy

Now

1. GT
2. LBP
3. Metal Gear Solid

This list looks on the money.

1. God of War 3;
2. Gran Turismo 5;
3. Home (had to).

1. GT5 [if not out then FF13v]

2. Killzone 2

3. God of War 3/Infamous

I think Kz2 will be a big seller and have huge legs. GoW3 will be the best seller in the series, as it's on a new platform and it is HD. Also, Gow2 sold pretty well. Last time I checked it was close to 4 mil world wide, I might be of a bit tho...

God of war III
FFversusXIII
JakIV

LBP is out this year, so cannot count it.

Also there is the secret RockStar game that's comming exclusivly to the PS3 on a 50g BD disc [it has been confirmed that it's not L.A Noir, nor the Western game]. Got a strong feeling it will be a GTA game in the vain of Vice City/SA, as the timing is right and they are keeping it very, very secretive. They also are doing the above 2 new IP's, so it leads me to believe this theory even more so. What do u guys think?
