Honestly, I've just been getting PS3 flashbacks the entire leadup to this gen. Sony feels like they're so unbelievably confident right now that they feel justified in this "radio silence followed by occasional spurts of information" strategy they've been doing for the past two years.
It also probably doesn't help that Jim Ryan is honestly just not a good public leader. I don't know anything about how he operates behind the scenes, but his public-facing interviews are always very bad ("why would anyone use this?", etc) and his presence in Sony events is markedly less charismatic than most of Sony's past leaders. Even Andrew House felt like a better showman than Jim does right now. Sony needs a better spokesperson than they currently have.
Now, for clarity, I don't like Phil Spencer all that much either, and I feel like his "tell people exactly what they want to hear all the time, even if you know you'll have to backpedal it in a month" strategy isn't the ideal way to sell a console, but at least Xbox is communicating with their fans. By comparison, Sony is acting like they already have this in the bag when Microsoft has been making a lot of very strong moves to knock them off their perch.
