[Update: Oh good! "The original version of Bayonetta will be available via a digital download on eShop when you purchase Bayonetta 2 (either a box version or digital copy of the game)," says Nintendo. Glad that's settled.]
This morning, we were told Bayonetta would be included for free with Bayonetta 2 when the sequel releases in October for Wii U. It has since come to light that the offer is apparently only valid for retail copies of Bayonetta 2, however -- not eShop purchases. Bummer!
That info comes straight from Nintendo's website for the game. I'm wondering if (and hoping that) there will be some sort of similar promotional offer for eShop users. Otherwise, retail it is!
This bundled Wii U version of Bayonetta will run at 60 frames per second. It features GamePad support (touchscreen controls and off-TV play), Japanese-language options (audio tracks and subtitles), and new Nintendo-themed costumes for Bayonetta, like the Hero of Hyrule outfit above.
