Will play, certainly: the rules fit casual game once in a while, much better than WH8th.
Will buy AoS: from what is released now, no.
I'm waiting for the release of a book which develops Exiles' fluff, which I will buy.
I also wait for a book to develop the Realm of Azyr and related fluff for new Empire, non-Slayer Dwarfs and Highborn Aelfs. Will buy, too.
What I will regret a lot from WH8th is not the rules, it is the fluff in a world so closely related to our medieval world.
