Both FF (16) and Opera (12.5) have recently unprefixed transitions, animations, and transforms

I could give this a go if you're not doing it.

These -webkit-properties are in at least safari development docs so I assume there's pressure to keep the prefixed versions working as well?

We need to make a bunch of behavior changes before we can drop prefixes on transforms. From memory:
1. Require units on perpective (function and property)
2. Implement transform function matching for animation according to the spec
3. Implement the 3D rendering context stuff properly (layer intersection)
4. Change background-attachment:fixed behavior.
5. Probably more.

We'd want the prefixed properties to retain the current behavior.

Yeah, I figured I should have made this into three different bugs for the three areas before even asking... I'm mostly looking at Animation at this point, and so far haven't noticed anything crucial to be missing. I guess I should write to webkit-dev before wasting too much effort though.

Good to know, thanks.
