Add my vote to Nimblewright and Cadaver Collector.
I'm a player and I hate fighting the Nimblewrights - at least when I'm fighting them. Ask me outside of the encounter and I'm likely to say it was a really cool fight with a really cool monster - but not during the fight. I think every time our group has faced them it was a very intense fight that could have gone either way. I love to hate fighting those things.
The Cadaver Collector strikes me a very interesting and unique addition to the undead collection of critters. Maybe not core material but it definately deserves to survive the edition change.
