To answer the actual question...probably neither. PS4 has already got an edge in the "being reasonable" department, but sales for both will probably still be high. The lineup for the coming 4 years will also be really important, seeing as a lot of people still bought the consoles later on, and then you can really see which one got the edge in the amount of good titles.
Regardless though, i think they will both do fine enough.
pretty much, but if I had to choose, PS4, definitely, the XBONE is going to suck, no good exclusive games, has all the features people hated about the XBOX 360 and it even spies on you, even Don Matrick (or whatever that douchebag was called), the guy who defended it so vehemently jumped the ship and ran off to Zynga.
