Data from Japan show that Sony’s (SNE) PS3 sales are up since the company cut the price on its latest game console.

The PS3 outsold the Nintendo Wii and Microsoft (MSFT) Xbox 360 for the week ending November 11. Some evidence shows that the console is also doing better in the US.

But, the improvement may not last. There are shortages of the Wii for the holidays due to Nintendo’s poor planning. It manufacturing should catch up to demand after the first of the year.

And, Sony does not have that one "killer" video game to drive console sales. Microsoft does in the form of :"Halo 3" which is still has hot a a cheap pistol.

Sony may be seeing an improvement in PS3 sales due to its lower price point, but Microsoft could still bring down Xbox 360 pricing.

The Japanese company has a long way to go.
