PS3 was the first HDMI-ready console. After it's launch, the 360 added the function.

There is rumor, that 360 going to copy slim model :)

they are not copying the "slim model", all companys do it to reduce costs, sony did not invent manufacturing cost saving

Neither MS or Nintendo made slim versions of their last gen consoles (i.e., xbox and gamecube respectively) whereas Sony did (i.e., ps2).

If MS did it this gen, they'd quite clearly be taking a page out of Sony's book.
