Together with the April Fools-ish (re-)release of 8-bit Bayonetta on Steam today (http://store.steampowered.com/app/567090/) there have also been hints at further developments for the franchise. (http://www.sega.com/14111219)
Could we finally be getting a PC version of Bayonetta 1? Considering that Bayonetta 2 only happened because of Nintendo I don't expect that game to grace any other platforms anytime soon/ever but the first game should be fair game no?
The background image on the Sega page also appears to be from Bayonetta 1 at least.
The game is now out on Steam: http://store.steampowered.com/app/460790/
