why people are sticking with there ps2 or there ps3 and not getting the xbox 360 and the Nintendo wii console?

do they think that ps2 or the ps3 are way better system cause last year sony was the king of all system and games and it was in first place and it will stay the way forever? will sony will become king again this year with there ps3? sony is now making ps4 because they know they will gonna win again and the next console war and it will be first again. i think that sony will always in first place cause there games and system rock. Microsoft and Nintendo will suck cause sony gonna win this war if you like it or not.
