There's always going to be two different opinions of how a gens sales should be counted.
1: X360 is 2nd because it held that position when X1 and PS4 launched.
2: PS3 is 2nd because it sold more overall (according to vgchartz) throughout the shelf life of X360 and PS3.
It's your choice which option you choose to agrue, either way there's no definitive answer.
For instance, in my opinion I believe PS3 is 2nd as both are still being sold at retail world wide and still relevant to consumers today. Just because PS4 and X1 launched does not mean that PS3 and X360 stop selling and all sales of either product are still important to both MS and Sony.
