I think the PS3 has the number one spot for consoles in Japan for a good while. MHG for the Wii isn't going to raise hardware sales by much at all (I'm expecting 70K - 80K first week in Japan) and the Wii might jump to 20K hardware sales, but theres still going to be the aftermath of the Advent Children Bundle. I believe that with all these big PS3 releases in Japan the PS3 is finally going to have some good hardware legs. Here's my prediction for a months sales:
Last week
PS3: 35K
Wii: 13K
This week
PS3: 26K
Wii: 20K
Week after that (Golden week, this is a complete guess because I don't know how big golden week is, so sales could be higher or lower for both consoles)
PS3: 35K
Wii: 30K
And one more week
PS3: 27K
Wii: 20K
