Nice thread, it'll interesting to follow throughout the year.
For XB360 vs XB1, I've noticed you're comparing XB360 2014 vs XB1 2021 which is comparing the 9th full year of 360 vs the 8th full year of One. I guess it doesn't matter much because even the 360's 9th year is kicking One's 8th year's ass but it's a bit weird since the other comparison are aligned.
Signature goes here!
