Having spoken with Alessio Cavatore attending the italian GT in Milan i could say that the rumors reported aren't even probable.
He totally denied (also being a little bit surprised and amused) all of them saying that seventh edition will get SMALL changes in the way of the rules.And that WHFb armies will get NO .pdf adjustments like 40k armies at the moment of the transition between 3rd and 4th edition.Armybook will be totaly compatible with the new rulesbook
He admit that units will get a +1 bonus for having a wider front and that magic will get a terrible misscast table (if you roll a double 1 on the new misscast table it will be "bye bye for you mage") .-..but all the other things were totally denied by him...he has said something like "more than rumors it seems a rumored wishlist"
He pretty confirmed that goblin will be redone with more accurate proportions,he also hasn't denied the reintroduction of forest goblin
DoW will'nt get an armybook...only an on-line official list.Chaos dwarfs....they haven't even decided how to do them..and some of them aren't even sure to reintroduce them...what it's sure is that there'll be NO new armies in the future,maybe olny reintroductions..maybe[/b]
