you need at least 1000 G and 49 achievements
not just one or the other >_<
Not exactly, you unlock the katana once you unlock any 49 achievements or 1000 Gamerscore but it will become locked and unlocked every other achievement until you get both.
To truly obtain it you need both, note that it doesn't have to be the original achievements - there was a lot about this when an update came out along with a lot of complaining.
