My conclusions, from reading these informative tech comparison / console war free-for-alls.
A) Microsoft's Xbox One is in serious trouble, right out of the gate...due to lower performance specs (at least on paper), higher selling price, as well as major public relation / marketing blunders. Microsoft managed to pull off a Trifecta, in this regards. Somehow I can't imagine this have happening if J. Allard had been at the helm.
-- or --
B) The theoretical performance advantages of the PS4 will not translate into the major graphical and game-play improvements that everyone is expecting, in actual real-world applications. Multi-platform games will be more or less a wash...with the deciding factors then becoming quality of exclusive games, as well as online features, content and multiplayer experience.
At this point, I think either is possible. However, I am now leaning towards scenario "A" as being the higher in probability. Of course, since all of us here on GAF are more or less "hardcore" gaming enthusiasts...we may be biased in how we are predicting these factors will influence the majority of video game consumers.
P.S. -- Yes, I realize these are not earth-shattering insights.
