It's quite essential now for Sony to hurry up and get those 3D LCD screens without the need for glasses into retail, at a decent price. As much as I am displeased with the fact that Nintendo has one upped them, it was a very smart move on their part and Sony must remain on its toes. It is very possible, or even probable, that after experiencing the 3DS people won't take as kindly to 3D with glasses.
On Microsoft, to complete the picture, my opinion is that Kinect will enjoy mild success in the beginning and then slowly slip away into 3rd place. They will only get into 3D when LCDs without the need for glasses are around and they will have to, once again, gather solid support from third parties due to their meager first party effort, which takes time and much money.
