Did the kid who got a 95m head start on the 100m dash win when it crossed the finish line at the same time as the pro athletes?
I think you posted this before...and I replied to it before.
Both consoles ended with about 80M when the 8th gen started. The gen started in 2005 and new console emerged in 2013. The Xbox 360 was out for ONE YEAR and only sold 5.5m in that year.
So, in your analogy Sony is the superstar athlete. Microsoft is the kid. Either way, 5/80 or 1/8 doesn't equal a 95% head start.
The kid did alright.
