Wii has it's biggest week ever (1.84 mil) and MK Wii passes 20 mil

I wonder if in 12 months time we will be watching NSMBWii overtaking NSMB.

I am doubtful, but it will probably pass it eventually.

NSMB has been consistantly selling about 4 million each year, so will likely be about 25 million total this time next year. I don't think NSMBWii can sell the 16 million it would need to catch up.
