My predictions for next week:
Wii will have a slight hardware-increase, with SSBB selling out(i won't predict actual numbers cause Nintendo has been really sucky with their software-production lately)
PS3 will have a moderate hardware-increase, but Devil May Cry will sell less than 100000 copies
XBOX360 will remain the same , the 360-version will flop. Maybe it will sell 5000 copies
