Gamespot's The Point: Why the XBone is losing
Warning. Salty language and armor your behinds from the hurt. This has been making the rounds on the interwebz like wild fire. Please don't shoot the messenger.
TLDR : Nintendo went for the casuals by making a tethered tablet and lost big because the casualcore was not bothered.
Microsoft was in full swing on R&D and design implementation on the XBone while the WiiU was getting shellacked. The backlash from the XBone reveal was not anticipated and preorder sales are clearly showing that the hardcore audience was not lost to console gaming whereas Wii/softcore is still up in the air.
