Ozzy Osbourne is so busy that he's already making plans for October 2015.

What they are exactly isn't quite clear, but they involve something called 'Hell Gate,' a project that's been announced via a Facebook page and Twitter account that aren't currently offering much information beyond a promise that it's "Coming October 2015."

Classic Rock Magazine notes that some fans are speculating that Hell Gate will be a theme park attraction -- possibly another collaboration with Universal's Halloween Horror Nights, which used Black Sabbath's '13' as the inspiration for a 3D maze in 2013.

No one from Ozzy's camp is talking yet, but it's perhaps worth noting that Hell Gate's Facebook page is listed under "Attractions/Things to Do," and it certainly sounds like a pretty good name for a Halloween metal event.

In the meantime, fans can look forward to Osbourne's new solo retrospective, 'Memoirs of a Madman,' which collects 17 of his biggest non-Sabbath hits onto a single CD; it'll be released Oct. 10, alongside a 2-DVD package that boasts an assortment of music videos, live performances and interviews.
