Bayonetta's demo will be arriving in NA & Europe next week on December 3rd for both 360 and PS3 users
The PS3 demo comes in at, 1,196MB, and will include a tutorial and "The Angel's Metropolis" level.
The Xbox 360 demo on the other hand has a 770MB filesize, and will include the tutorial, "The Angel's Metropolis" level, and the "Falling Clock Tower" prologue level.
From what I gather, things are not looking good for PS3 owners, sadly. The omission of the Clock Tower level looks to be down to it looking a rough around the edges in comparison to the PlatinumGames developed 360 version. This Clock Tower prologue level is said to be extremely intensive on hardware, on both consoles, and that the Sega developed PS3 version seems to pay the notably higher price...
Both versions of the demo will include options for camera, sound and display adjustments.
"It will be more than just a demo that's pulled from the middle of the game. We'd like to make it so that those who've already bought the game will make new discoveries if they play the demo."
Sega have released three screens for each version. At this size little distinction between the two can be made, but I will post them anyway. There has been a little fuss over the second image in both, as they do look exactly the same!....Make of that what you will.
Expect the demo to hit in early January in the West.
