I dont think it's fair to compare 10-15 hours long game with 50-60 hours one.

GT4 released in Q4 2004, which would make it 5 years in developement if the rumor are true. While it would probably take a lot less time to make a second GT for the PS3 than the first, say 3 years, it would push it to 2012, so maybe Sony could decide to make the next one a launch title for the release of the new Playstation system. Would certainly give it a nice boost right at the start.

I love how almost every big budget game is PS3 exclusive or at least on PS3. Can't see likes of 360 and Wii supporting big budget exclusive games.

Maybe because they realize it's not healthy for themselves or the industry?

There's no real way to know. Not even roughly. It's just guesstimates all up and through this thread. The only ones who know are publishers and the like. We don't know how much games cost unless someone tells us, so speculation of game costs is fruitless.

If I remember correctly ... Halo 3 was a pretty big budget exclusive XBox 360 game; and games like Oblivion and Bioshock were released on the XBox 360 long before they were released on the PS3. In fact, being that the XBox 360 sells dramatically more software than the PS3 it is fair to say that it has a better chance of supporting big budget exclusive games than the PS3 does.

On the other hand, "Big Budget" on the Wii means something that is quite a bit different from what it means on the PS3/XBox 360. Being that development costs on the Wii are similar to previous generation games, developers have claimed they're 1/4 to 1/2 the size of HD games, and the Wii has sold more third party software at a similar point in its life than the PS3 or XBox 360 does even though it has not received the "quality" third party support, I think the Wii would have no problem supporting quite a few "Big Budget" exclusive games.

You make it sound like that's a good thing...

Sure it seems great, however if Microsoft/Epic can make Gears for 10 million and Sony need 60 million for Killzone you can easily figure out who's more successfull. And more money means more means to invest in new games.

You can be sure that Konami won't ever do something like MGS 4 exclusive again.

We don't know how much Killzone 2 costs.  Let's not be absolute in terminology then.

I love when devs take their time to make games better. Thats why many don't anticipate for R2 and Gears 2 and countless other games which are released every 2 years as much as likes of GT5, KZ2, MGS4, GTA4, HALO3, TRICO, ZELDA, RESIDENT EVIL 5, and FINAL FANTASY.

So for me and many others quality is important and we don't care if R2 outsell KZ2, it will not make it better FPS.

 Could you please read the thread. We know the costs for Lost Planet, Gta4, Stranglehold and Gears of War, none those were ''guesstimates''. They are however reasonable bench marks to then make estimates about other titles.

Shanbcn that is actually very bad for the companies developing on PS3. Games don't sell as well as they do on the 360 and development is far more expensive than on the wii. Why are there still these titles on PS3? Because a lot of these projects were started before it was known Sony would be in 3rd place. Those big budget titles you speak of are purely left overs of companies that couldn't take the title multiplatform. FF13 went multiplat because S-E needed the extra cash because the PS3 alone wasn't enough. MGS4 certainly appeared to be somewhat of a dissappointment for Konami as it was hugely overshipped in Japan. The development costs were clearly far far higher than previous games yet sales weren't.

The question is why has development on these PS3 exclusives taken so long? Gears of War 1+2 have come out before KZ2 and seemingly will support more features having split screen, online co-op and in GoW2 horde mode. Not only that but KZ2 doesn't seem to do anything that would justify that extra time over GoW2.

And like Bengabenga said if games can be made much cheaper on the 360 then companies are making a bigger return on it. There have been big budget games on the 360 but they have been much quicker to come out and so cost less. Just look at games like Mass effect.
