Well since you asked so nicely!
PS4-It's going to have a great holiday season beating out the xbox one in sales due to the price diff
Personally- It's going to be my first next gen device so I'm looking forward to it. The 1st party lineup is okay, needs more.
Xbox One- Going to do relatively well the holiday season also
Personally-Exclusives look great, but the starting cost is to expensive for my taste. As for the drm thing, maybe since once ms reels everyone in, they can start slowly transition towards there goal. It would be like a captive audience. There next console afterwards could go forward without as much resistance. I don't think they will completely abandon the strategy, but who knows really.
Wii U-sales should pick up due to games, how it will do lifetime is yet to be seen. It could end up doing a bit better or worse then the gamecube.
Personally- It doesn't interest me much at the moment. Just doesn't scream must get or next gen. The tablet controller is meh too. I might pick it up down the line for some games though.
