For all of Sony's Generations, we have always had a new format introduced to the gaming world.
The PS1 used CD's.
The PS2 used DVD's (could play CD's), which made it have a nice appeal to get a complimentary DVD player with your PS2.
The PS3 was capable of playing Blu-Rays (could play DVD's and CD's), but had little appeal to consumers because of the price.
So, will the PS4 have a new format? If so, what will it be?
If you don't think the PS4 will have a new format, why?
