The 360 has not come anywhere near KZ2 in terms of graphics and physics, therefore Killzone 2 can not be replicated on the 360 to the same standard it is on the PS3.

The 360 isn't at the start of its life either, so it isn't as though we'll see massive graphical jumps in games.

That's not true... GG was tapped to do another game for the PS3/360... it was a sequal to one they did on the PS2/Xbox

yea, I think they should stop doing that - it's unsightly

but well, I chose to ignore interviews like that and don't let them bother me

 it's saying things like this that come back to bite you in the ass

You know it never hurts to add a imo when discussing something as objective as looks.

IMHO it only comes down to the Skus and the wider range of possibilities they provide.

I would say it's fairly legit for those dev to claim their games, as they are, would not run on the 360... PS3 7 SKUs are capable of handling different tasks at the same time and without interfering with the main processor. The 360 has namely two processors (one divided in two) as powerful as these two processors might be they still have data processing limitations.

I'm gonna apply a Formula one analogy here : when a race car makes a pit stop you have a mechanic allocated to each task to perform, one who unscrews the bolts, one who changes the wheel, one who refills the tank and so on (that's the Cell). This method allows not only to be more efficient but also to be faster. Now say instead of these seven mechanics you have only two at your disposal. If you want to perform the same level of maintenance it sure gonna take more time and be less efficient because a mechanic, as strong and fast as he is, has only two hands so If you want to stay competitive then you have to make choices and give up some of the less vital tasks.

That's why games which take full advantage of the PS3 Skus cannot fully run on the 360. That doesn't mean a 360 version is impossible to do it's very much feasible but only by making compromises. At least that's what I think.

They are SPUs... they are asynchronous  processors(they don't run all at the same clock rate).  The Cell has 8 of them per Cell Core.  For the PS3 one is used for extra to increase yields and another is used to run the OS... That leaves 6 SPUs.  In order for someone to get those SPUs to run at their best (ie. KZ2) they have to put an extra level of effort in the development of the game.  However the PS3 has far more bottleneck than the 360.  The effectiveness of the Cell as a gaming platform will never be truly realized this gen.  It wont be until the PS4 that you see some of the PS3's weaknesses(separate RAM and GPU issues).  Your Formula One analogy doesn't work in the world of mixed memory and last minute GPU addons.  If any can be applied it's simply that the PS3 has the highest possible max speed, but the Xbox 360 has the better driver(ie. development tools, dev support, familiar archtechure)

Oops, yeah I meant SPU not SKU...

You say the strengh of the 360, opposed to the raw speed of the PS3, is having the "better driver (development tools, dev support, familiar archtechure)" but that's only a temporary advantage isn't it one that lasts until dev become familiar with PS3 programming and when proper dev kits are released. What will happen then ?

When I see statements like that, I don't think 'Oh how impressive a game that requires a lot of performance to run' I think 'So, all the game has to rely on to impress me is visuals?'

When I see statements like that, I think, "So you made a game that only runs on the least popular console of the generation?"
