While Sony is pushing for 3D-with-glasses, Nintendo is going glasses-less 3D on handheld.
Microsoft is really at advantage here to pick up the glasses-less home theater/console.
Why didn't they go that way? Are they leaving it wide open for Nintendo to dominate that angle?

how can you be sure 3D without glasses is going to work well?

atleast wait for it to release, Nintendo haven't shown anything for goodness sake.
