In animated, Slag (triceratops) was renamed Snarl and used as a third member. Sludge and Snarl (a bronto and stego) were dropped.
And I should point out that there's nothing really wrong with Prime. It's one of the best TF series I've seen in a very long time, but it's another reboot of the series and as such it's going to be a free for all where names and characters are concerned. The Prime Wheeljack, I was pleased to discover, does resemble his G1 counterpart, but behaved more like Springer (VERY much like Springer, in fact...hmmm). Even so, I encourage you to watch it. The season premier's in about a week or so so there's likely to be a season one marathon some time around that.
And on a side note - has anyone been keeping up with toy releases related to Fall of Cybertron? Rumor has it, we're getting a full 5-piece Bruticus made up of separate deluxe class Combaticons!
