DivX, Inc. today announced that DivX« video technology will be integrated into PLAYSTATION«3 (PS3™) from Sony Computer Entertainment Inc. (SCE). The popular computer entertainment system will be added to the ecosystem of devices that currently support DivX video playback. To date, over 100 million DivX Certified« products have been shipped into the market, and it is anticipated PS3 will significantly expand that number.

Now the question is will the Xbox 360 also add DivX? The only reason I can see why it wouldn't happen is because DivX is a competitor to Microsoft's WMV, and Microsoft would not want to encourage DivX usage over WMV. Sony has no such problems because they do not have their own video format.
