y porcierto NOSE PUEDE ACTULIZAR A DIRECT X 10,principal motivo: el hardware, segundo, el s.o.
ATi confirmo que si. El hadrware es tambien shaders unificados y el OS es atualizable asi que no hay impedimiento para una actualizacion por soft
"There could be a change for the XBOX 360. ATI recently announced that on the 360 it's possible to install DX10 by an update. It could mean a lot of DX10 games coming to 360, especially with XNA and cross over programming. It looks like a clear case when Microsoft is talking about Live anywhere. If new games will use DX10, it would be more then likely that the 360 runs DX10."
Y lo del Dx9L no tiene que ver con eso, ese fue un rumor de the inquirer que volo hace unos pocos dias pero que no se relaciona con esto
edit: aca esta mas claro y tenias razon

"Xbox360 cannot run DX10, and confirmed what I said earlier about the extended functionality.
The Xbox360 has unique features including memory export that can enable DX10-class functionality such as stream-out," said an ATI spokesperson. "From what we're hearing, Crysis will support DX9 with some sort of use for DX10 features.
It's likely that those DX10 visuals can be replicated on the Xbox360, but it can't be properly called DX10."
Conclusion, no puede correr directx 10 tal cual es directx 10, pero puede con su version particular del directx 9+ efectos similares al del dx 10
Osea que es casi lo mismo pero con diferente nombre. al caso lo que importa es que se vea igual y no como se llame aquello que corre
