"Secondly, today's news suggests that Revolution will ship well after Sony's PlayStation 3, which is rumored for a first quarter 2006 debut."
If that's true, I see that as being very good for Microsoft, considering that the technological gap between the two would likely be rather small, if there at all, as Sony is rushing their console for a earlier release date while still being shown after Xbox 360. Again, assuming that rumor is true, of course.
