The news marks a first for Sony on its home turf also given rise to the prospect that Sony may return to it former dominance over the last 11 years.
One analyst remained skeptical, however, saying one month is hardly enough to forecast a turnaround. "Overseas, I don't really see the PS3 doing that much at Christmas time primarily because it's still more expensive than the other machines and has less software," said Hiroshi Kamide.
"It's nice to see the system selling much better than six months ago. But is it a sustainable trend? Is it going to really escalate from here? I'm not so sure."
