that`s cos the publishing houses of Jaglan beta farmed the typesetting out to the Syrius cybernetics publicity division, who passed the work onto Alvin (Marvins prototype), they are also handling the moulds and assembly of the Pandora, an event eagerly anticipated across most of the civilised parts of the western spiral ARM of the galaxy, the manual is being written by a team of top authors, Oolon Koloophid, Prosthetnic Vogon Geltz, Ford prefect and Arthur Dent, Zephod Beeblebrox is editor.
Erotica Gallumbits is working on what she calls "entertainment software", Frogstar are providing the firewall and Hotblack Dessiato is doing the startup tune, however due to the developers being stuck inside an event horizon (Zaphod was drink driving..again), the release date will be two months from now, where now is defined as the time Zaphod allowed the Heart of Gold to get too close to the black hole plus the mount of time they have been inside it from our perspective.
so it`s highly improbable it will be released this year, unless something improbable happens, which it probably will.
this has been taken by most members of the more relaxed planets in the universe to prove the non existence of God, God is not convinced of this, and has published several rebuttals entitled , "who am I?", "I think therefore I am", "without faith I am nothing" and ended it with "are you sure? oh well, time to retire then", thus proving his critics right.
