I was able to get the Closure/Continuation from Importcds for $63, including shipping. Though pricey for a single title, I must admit I've paid more for deluxe editions - however those are usually for classic and well known titles I really want. Thankfully, the pre-release songs are good and early reviews are extremely positive. Given SW's excellent surround mixing and production skills we know the album will at least sound great, and for fans of PT who had mostly given up hope of hearing anything new from the band, I think it's good gamble.
Also, the blu-ray appears to be pretty loaded with content (96kHz /24-bit stereo, 5.1 and Dolby Atmos mixes of the entire album, three bonus tracks, instrumental versions of all tracks, etc.) so it seems like fairly good value even for those of us who don't care about standard resolution cds or "art" books. I've also read some interviews that indicate C/C could well be Porcupine Tree's "official" swan song - I haven't read anything that indicates that the band has committed to doing anything else beyond this album and the upcoming tour, and none of them appear to be putting their solo careers or other projects on hold.
