^Have you seen what PS3 games are coming in Japan during January-March?
Anyway, time will show, but i think PS3 will stabilize at 30k+ for the most of time during 2010.
I also expect Wii sales to go to PS3 levels, when PS3 cost 40k yen. Because, i think Wii already saturated Japan market at some point.
Now it`s PS3 showtime!
