Don't worry, it is coming soon. The reality is that SEGA only ports things they feel, could choke more money out of, and that depends on the selling point. Other games are made to just make you buy the game console itself. The way I see it, is that if a game is not being ported to PC, it is because they do not feel it is time yet. Also by not porting protects the purchase of the player, meaning SEGA can reuse it's IP at a later date, in case of emergencies as with Capcom and Resident Evil.
Besides, the only reason why we would want a port of Bayonetta, is so that we would mod the living daylights out of it. Like all the female skins could be nude, and have extra big boobs. Looks like a freaky Vash the Stampede.
