When will the PS3 sell more software units in NA than the 360?

The PS3 will never catch the 360 in software or hardware in North America.

 /Agree, the huge gap that seprates the PS3 and 360 is almost all from the U.S and the gap is closing; but only due to WW sales. The PS3 most likely can beat the 360 WW if it manages to maintain its current rate.
