One feature I'd like to see in Bayonetta that may not be brought up otherwise is making recordings of the game and perhaps the ability to save, upload, or send these videos to friends, a leaderboard, or perhaps even youtube (PS3 is capable of this, as demonstrated by Pixeljunk Eden). Ninja Gaiden 2 also had this feature that allowed you to save videos of gameplay and upload them to leaderboards for others to view.

Considering the reputation of the developer and some of the already crazy videos that have been uploaded for similar games (especially the Devil May Cry series), this would be an amazing feature to add to Bayonetta.
