or are they both expected to be disappointments?
Both disappointments. But xbox is far worse.
How is the PS4 a disappointment (apart from the issue with the analog sticks)?
I doubt people will actually expect the PS4 to surpass a PC. Calling it a disappointment less then 24 hours after the launch isn't really a constructive comment imo. The sales numbers will probably say otherwise. I think the PS4 is a really promosing consoles, with great exclusives in development. PC will always be superior when it comes to graphics/possibilities, but I'll always prefer a console.
