Campagnolo Neutron rims?

Any Campag experts know if the rim design was changed when the more showy graphics were introduced in 2007-2008? I have found a new rear rim but its an older version than my worn out one. I know the 2013 rims are different. Thanks

I don't own a single Campy bolt even but one day I plan to be a fat banker and ride a Serotta with a 25cm head tube with full Super Record gruppo.
