Crunching the numbers (basic algebra for the win!), we get average monthly sales for each console at:
Wii: 121 million units/28 months=4.32 million software units per month
360: 124 million units/40 months=3.1 million software units per month
PS3: 49 million units/28 months=1.75 million software units per month
