When asked why there's no 80 GB PS3 in Europe, David Reeves responds that the difference in size is just not worth it.
Not doing SCEA any favors, the SCEE President commented in an interview about why Europeans would be getting the console.
"You know, the difference between 60 and the 80 gigabyte is very small. We just feel that going up 20 gigabyte is not worth it. If you're going to double it, it's worth it. So maybe you'll see something a little bit later, but 60 and 80? Really not much difference."
