PS3 slim came out 3 years after the PS3 launch
I bet I know whan the PS4 slim will arrive
is it in 10 years? must be.
im thinkimg more like 2 years
It hasn't even been a year since the PS4 came out... what makes you think that Sony would rush to make a PS4 slim?
New models reduce production costs, more power effeicent, in some cases like the PSP some minor improvements in preformance.
