You forgot the fact that players can also play some of the new games like titanfall on the computer, and that both consoles is built for graphics...
The thing players might hate the most is when the publishers like Sony or Microsoft buys of the rights to the game franchises we know and love just to ruin our fun by forcing us to decide what console we should get, do you really want to spend a bunch of money on a console that only has one game you like?
Didn't the ps4 fans hate it when they got the news that DR3 was a Xbox one exclusive?
