i will not buy the next splinter cell, very simple!

Technically, going by specs, the PS3 can do anything the 360 can do, and in many aspects it can do those things much better. But it's all but what the developers optimize. If a developer optimized their game to fit the 360's capabilities, it might not be possible on the PS3, same on the flip side with the PS3, especially when you factor it what the Cell can do. Ubisoft is obviously being paid to say this stuff. Either that, or they're satisfied with the money they make from 360 games, so they won't put out the effort on the PS3.

Strictly speaking, I don't see why any game can only be done on one system and not the others. True it may be harder to straight port a game than last gen with the vast differences in CPU's and RAM this gen but all that means is they would need an entirely new engine. That means the specs of the 360, PS3, or Wii isn't what's stopping them, money is (for the new engine and any money from Sony, MS, Nintendo they would lose). Of course "we're cheap and/or bought off" doesn't sound as good as the "PS3/360/Wii can't handle the awesome things we're doing".

or they're just lazy and/or go for the system with the biggest user base =)

 Where is my Rainbow Six and Ghost Recon, I want them now on my PS3!!!!!!!!!!!!!!!!!!!

ps3 can`t run some crappy game with average grpaphic? LOL. Just wait for MGS4, it will own SC5. =))

If they can't pull off that game on the PS3 and others are pulling off much better looking games it means the problem is with the developer. Look at that game then look at GTA IV

I wouldn't say it this way. It can be easier and cheaper to use the tools for one plattform. Microsoft offers tools, that work on the Xbox 360 and on PCs, but not on the PS-3. If you want to use these tools (which make parts if the development cheaper) then a cross plattform development for the PS-3 could be more troublesome and expensive (rewrite parst of tzhe APIs, flatten the code to the PPE and try< to find code to be exported to the SPEs).

I would think the comment has more to do with the costs, not really with the technical capabilities. I don't really think that any game could really say that it was not technological possibele on the PS-3 and Xbox 360. Their technological differences are not as vast as some people think, but for programmers the technological possibiklities of the hardware are only one factor. costs are a much bigger.

The problem for the PS-3:it is advisable to write programs first for the PPE and then port parts of it to the SPEs. This PPE code can be ported easily to the Xbox 360 (complex underlying APIs would be a problem for the SPE optimization). This is not true in the opposite direction. If you don't have the underlying APIs you either have to rewrite them or rewrite the code.

 Factor5 flat out said 360 cant run the same amount of Progressive Mesh as PS3 can, thats why Lair in its current state could not be done on 360.
