A senior UK source has told VG247 that a slim version of PS3 is "100% real".
The comment was just backed up by another very senior UK industry figure.
The machine will release in "Q4," we were told today.
On the question of when we're going to see the new SKU for the first time, the source simply said, "Pass".
ArsTechnica rumoured earlier this afternoon that the machine was a reality, but that no announcement would be made at E3 next week.
