It should be noted that the 360 was released a year earlier than the PS3. This means that the PS3 has already defeated the 360 in sales-per-year by a rather substantial margin. This is due to the fact that the PS3 is catching up to the 360 in the US but dominating the European and Asian markets. It would also be wise to take into account the amount of 360 consoles that were purchased multiple times due to defective RROD units.
