Can games using directx 10 be ported to the PS3?

Conversely! Could a PS3 game be ported to the a DX10 PC without dropping any effects?
'Without dropping any effects' is a hard one to answer as it depends how they're done and what resources are used. eg. On a PC game using DX10 requiring a 512 MB DX10 card and 2 GB RAM in the PC, it's not unlikely that certain aspects of the game will be dropped. However, porting a DX10 game incorporating the abilties of a DX10 class GPU is something PS3 should be able to handle quite well thanks to the versatility of Cell.
As an example of DX effects on non-DX hardware, PS2 hasn't any pixel shaders and barely classes as a DX7 part, but GOW on PS2 has some excellent reflections (best in class) that would use pixel shaders on a DX9 GPU. You can use different techniques to achieve the same results.

That's a bit of a silly comment..
Just because the RSX is based on a DirectX/OpenGL based PC card, doesn't mean that the RSX is a DirectX GPU..
Surely considering the fact that such a GPU was developed from the ground up (using the G70 as a reference) AND the fact that the designers had in mind the fact that the GPU would never run DirectX from the get-go, means that they would have designed the G70 reference, stripping out all DirectX processing capability and ramping up the OpenGL ES based processing bits, modifying with power and heat reduction in mind.. I can't imagine the RSX is a DirectX GPU by ANY means otherwise wouldn't that be an incredibly stupid waste of silicon?
Sorry, but you really have no idea what you're talking about. It's scary how confused people are over what DirectX means in relation to hardware. The same bits used for DirectX are used for OpenGL. Stripping out the DirectX bits would leave an empty die!
One thing is sure, D3D10 games can be ported over Babbage's analytical engine with just a little stretch of imagination
Effects that really really require integer processing, if such a thing actually exists, would be very difficult to port over. Other than that I don't think there is anything in DX10 that a PS3 just couldn't do one way or another.
It has less memory than a modern PC and a whole lot of stream-computation potential, and that will have far more differentiating impact than that silly DX thing.

This is an artist's conception of the difference between a dx9 and dx10 game:

I could swear that the last time I saw that picture the top was labelled "DirectX 8" and the bottom "DirectX 9".
As I understand it, rather than giving your "new effects", DX10 gives you new and faster ways to implement existing effects, existing effects being pretty much anything as a DX9 GPU can probably render anything, its only limited by the speed at which it can render it.
So if a particular game used DX10 to create graphics which would be much slower using DX9 methods and that game pushed the limits of a decent DX10 GPU's power, it probably wouldn't be possible on PS3 without compromises.
Thank you for the reasoned reply, and not just "lol".
What about heavy use of dynamic branching? RSX as a G70 derivate should be pretty lame doing that.
Also I don't think you can emulate the geometry stage on CPU without suffering performance greatly (especially if filtered texture lookups are used as an input).
this has nothing to do with D3D10, it's not a requirement to have a particular dynamic branching implementation, it has just to be there.
It depends, if you try to exactly mimic on a CPU what a GPU does then you are going to fail for sure.
Texturing can be done in so many different ways.

Hmm don't really think its possible
Crysis looks like it's surpassed Xbox360 and PS3 already
And also PC will always be ahead of Consoles its simple as that
PS3 and Xbox360 might win over PC for the end of the year
But HAVE! you seen the new G80 Cards it flippin massive thats the only reason why consoles sell no need to upgrade a dozen times and also no need to worry about system requirements.
I know PC will always win its just that people can't get over it
I might get flamed for this post but it's true
PC is a different beast to consoles no need to compare them

Then why did you?
What gives you that idea? First gen D3D10 cards (G80/R600) should handily spank any current cards out in DX9.
