The 'yay no vendor prefixes!' crew seem to have very short memories on what it was like before vendor prefixes..IE Waiting a LONG time (years) for a CSS feature to be 'recommended' by the w3c.
Vendor Prefixes were the best of a bad situation, I think they will be missed quite quickly.
I'm all up for this movement, but the W3C will need to move a lot quicker if this is to happen. Otherwise innovation will just grind to a halt again like it did before.
