Japan is such a weird market right now who knows what will happen down the line with PS3. ONe thing that Nintendo has to worry about is keeping their appeal up in Japan with the Wii. Otherwise PS3 will pull a PSP(although the changes are for different reasons).
But it's really not about weekly sales for PS3 in Japan. PS3 needs to prove it can be a big holiday seller in Japan which after 2 holiday seasons it's yet to prove. If it can't do that then no matter what it does on a weekly basis can get it on a good average.
But PS3 should do a little better after MGS4 in Japan, or at least I would think. Nintendo brand is struggling a bit in Japan lately mainly because Nintendo has seemed to ignore it for awhile. Nintendo needs to put out a new model of the DS to replace the oversaturated model out there and needs to get more Wii centric Japanese titles out there. If not then PS3 easily can start doing a lot better.
