This has the potential to be a real leg up for MS in the console war.
I was one that actually found Kinect to be awesome for getting into shape and went through Your Shape and EA Sports Active with great success. Lost weight and toned myself. It worked for me because I can't discipline to drive to a gym and morning workouts in front of a TV were perfect. Plus the tracking was a real motivator to keep me going.
Now you've got some of the top trainers on board, Kinect 2 with better tracking and heart monitoring. And the real game changer is THIS is the type of stuff that you'll see on the Today Show, Ellen, and elsewhere. None of those places are going to promo the newest FPS shooter but something like this will make the rounds. Parents see it as a win/win - kids asking for a console and this is something they can use to help justify the purchase as it shows it could be something to benefit them too. Not to mention all the TV stuff, fantasy football, simple voice commands for Netflix and you can start to see that if you can interest those pulling the purse strings then it could be something to tip the scales with all else being relatively equal. From a parent standpoint the tip of the scale for PS4 is price, but if they see the value of things like this then it may equal out. The other big factor will be how easy either is going to be able be found on shelves this holiday.
Very true. I think it really comes down to how well Microsoft markets these kinds of things around the holiday season. They need to make it clear to non gamers that this is the console that non gamers can and will enjoy. I also believe that with the games coming to the X1 it's going to be the console to have for gamers as well, but like you said, the non gaming/parent crowd won't really care about that.
