There aren't any more details at this stage. (I'd hope that the downloadable version is in a high-bit-rate open format, and not, say, DRM-shackled .WMA files, and for £40, you'd hope that you get something more impressive than a double jewel case with a booklet.) There is also no news on how Radiohead will make this available to people who aren't on the internet or don't like buying things online. I suspect that a deal with Starbucks is probably not on the cards, though.
The 40 pound option IS much more than a double jewel case. It contains 2 CDs (one with extra songs that aren't on the album, and digital photos, lyrics etc), 2 12" Vinyls of the album, a book with photos and other stuff, and all in a slip case. The design is pretty good too. I've ordered my copy. Will ship around Dec 3rd.
...AND, it includes the digital download on Oct 10.
Personally I prefer CDs and wish they had a normal priced single CD version available. I wonder if they ever will?
However, I think the idea is fantastic, it just doesn't fully suit me.
If the digital download is available in lossless I'd be happy enough with that. Not sure what I'd pay though. It depends entirely on the file format.
I would be very surprised if a standard chain-store single CD wasn't available at some point in the near future - it would be quite revolutionary if it wasn't. However, not being signed to a label, I wonder how they would do that?
Ideally they'd offer the download version in a variety of formats and bit-rates.
This is an interesting move from Radiohead, I wonder if this will set some sort of new precedent? They're not the first band to do this, but they're definitely one of the most prominent I can think of.
