It's nothing more but a temporary bump in sales. It will probably calm even out and then go back to usual when the PS3 matches the 80gig price with the 40gig.
Japan has a Sony fan base, they will try the 360, but it won't stop them buying a PS3. After the TGS, expect a big bump in PS3 sales in Japan.
In fact, expect a big bump in PS3 sales everywhere after TGS.
1 week improvement in sales is good, but not as good as better ongoing sales. It took a price drop to compete against a higher priced console with a smaller games library!
