Yeah I could see it happening. Not sure why everyone keeps doubting this system in regards to sales. Its shown to be a stronger seller than the wii and Sony has proven they have more production capacity. In addition to that the system is still undertracked. I wouldnt be surprised if it did 21-22mil, just for the fact im predicting 20mil (always beats my expectations by at least a mil). People need to stop comparing this to other systems and saying it cant sell x amount for whatever reason. We are seeing gaming history in the making and this system is setting the new bar whether some want to admit it or not.
