The Warhammer 40k Digital Rulebook just went up for pre-order on ibooks to be released on th 20th of this month. Just the basic rulebook, no frills, but exactly what a lot of people are looking for. I for one, am very interested in on how the wording of Puppetmaster is in the digital rulebook. (would very much solve the issue).
A big thanks to the following guys for helping us all stay on top of what is going on. Don't forget to check out their blogs as well (well placed plug).

The iPad 40k rules sample has a full glossary.
Since I can not find any glossary in any other sample ibooks, I feel this may be a mistake from GW.
