I think that most people here take for granted that Xbox One will fail and sell considerabily less than PlayStation 4.
In reality, Xbox One is starting this generation in a much better position than Xbox 360 did.
At the time Sony held LOTS of important third-party games as exclusives or timed exclusives.
Final Fantasy was basically a Sony exclusive (no, Crystal Chronicles does not count, sorry)
Metal Gear Solid too.
Kingdom Hearts too.
Namco was literally in love with Sony (Tekken as an historic exclusive of the Sony consoles)
Grand Theft Auto was a Sony timed exclusive.
Capcom was publishing lots of Sony-exclusive games.
Right now the situation is DEEPLY changed, Xbox 360 is the best selling console in the US, it managed to build its own library of games, has a very active (and loyal?) online base and, on the other hand, "PlayStation" is no longer the synonym for "videogame" in Europe.
So... why is Xbox One already deemed as a failure? Are you guys REALLY sure that the large mass of buyers care about 180° turnarounds, behind-the-curtain stories and funny animated gifs?
90% of buyers will simply buy the console if they are interested in it, regardless of whatever happened (or was about to happen) BEFORE the console arrived on the shop shelves. And this people will decide if the Xbox One will be a success or a failure. Just them, not a bunch of informated/passionate people writing on NeoGaf.
I really can't wait to see how the console will perform. I think it will be very, very interesting.
