I do like the new avatar models and think they have added to the Malifaux game. The manifestation of the avatar is in interesting change to the end game and for 2 SS they are really a must have. I have only had one game using an avatar, The Neverborn Avatar of Fate and it was a very enjoyable game. They definitely add a centre piece to your crew from a modeling perspective.
I wonder what is next for Wyrd, as it seems that Malifaux has had enough expansions and enough model to last for ever. Maybe a new faction ? Although I'm not sure what it could be themed on. Maybe a new miniature game using the fate card mechanic (I think its excellent) but with a different theme e.g. Sci Fi Malifaux? Puppet wars doesn't interest me but a new miniature game would.
