There isn't going to be an explicit version. It's been obvious from day one. As another member stated a few weeks ago, they allowed the explicit version to leak in hopes of building up hype and interest. Then, they released the clean version as the one and only official version of the song. It's kind of smart because they don't have to make a separate radio edit, and it will chart as one song on the digital charts (versus the explicit version reaching, say, #12 and the clean version reaching #30 on iTunes).
They wouldn't be selling separate explicit/edited versions of the album on Amazon if they completely scratched the original lyrics in the demo.
UK single releases are always pushed back as late as possible to gain alot of radio support. So I don't think the single will be released until near the album's release.
ahhhhhhh
