Hi I'm planning on buying a PS4, and selling my Slim PS3 System for a number of reasons. I won't list them here but the moral of the story is; I want to upgrade the system to play some of the future titles on the Play Station. The PS3 still produces games time to time but they are mostly indie games. Even if I still sell the PS3 System I still have two PS3's backwards compatible with PS2 Games (Long story short me, and my Dad bought three PS2's, and traded them in at GameStop to get a free upgrade to a PS3.) So we can still watch Blue Ray Movies, and play PS3 Games, PS2, etc... Without paying for a game streaming service, So I was curious if there were any Diffrent models of the PS4. Similar to the PS3 there was a fat PS3, a Phat, and a Slim. With all pro's and cons. I was curious if there were any pro's OR cons with the Diffrent PS4 Models.
