Although the PlayStation 3 version of Bayonetta is a bit inferior in comparison to its Xbox 360 counterpart (see Famitsu scores), sales for the PS3 version have more than doubled that of the Xbox 360 version in Japan.
The PlayStation 3 version of Bayonetta sold 93,000 copies, whilst the Xbox 360 version sold only 45,000. Not surprising, considering Japan is more prone to technology made in their country to begin with.
