Kinect 2 really won't be THAT expensive. If you count in that the ps4's APU and memory is slightly more expensive the difference in cost won't be over $20-$30. I think they wanted to make profit on each system sold from the get go, with SOny selling the PS4 at around cost price.
Don't be so sure yet though, i wouldn't be suprised if MS ends up matching the $399 in the end.
