My thoughts
MS:
They seem to be doing whatever they want regardless of how much negative feedback they're getting from gamers. It's been non-stop barrage of negativity towards MS since they confirmed all the bad stuff about Xbox One. It's restrictive, not consumer-friendly and expensive. Do not want.
Sony:
Pretty much came out and capitalized on the poor reception of the Xbox One. $100 cheaper, trading/selling games is the same as always, no online required, etc. I feels like they listened to consumers and gave us what we've asked for while MS seems to be doing whatever they want, regardless of what WE want.
Nintendo:
A predictable and weak showing from them. All of the big titles they announced are 2014 releases. Why should someone buy a WiiU this year? Pikmin 3, Wonderful 101 and Watch Dogs are the only WiiU titles on my radar through this year. If they could assemble a strong lineup of games, especially some new IPs and 3rd party exclusives they would be in much better position. Next year is looking great though with stuff like Bayonetta 2, Mario Kart 8 and unnamed Monolith RPG. Hopefully they still have something left to show us at E3, like Metroid, Zelda, Starfox, F-Zero, etc. I really felt that this was the make or break moment for the WiiU and they totally dropped the ball.
