RPMs Mini-vehicles listing.
With the recent wave 3 items shown at tfw, I was able to put this list together, with a little help from tfarchive.com on a couple of blanks.
RPMs are the sub-line for Transformers, so that Hasbro can break into the 3 markets of die-cast cars (Mini-vehicles), remote control cars (RC), and toy cars for the younger age demographic (Battle Chargers).
With the Mini-vehicles, the die-cast cars are being released in single packs and double packs, with the gimmick of the robot mode moulded to the underside of the car (so that you know for sure it is a TFs toy, even if it doesn't convert).
At this stage there are 12 single packs and 8 double packs, with four vehicles that appear to be in both single and double packs, either exactly the same, or with a very minor redeco. And 3 of the single-pack vehicles are heavily redecoed in the 2-packs.
Each pack is numbered in a series.

TRACK SET
Constructicon Devastator Track Set (w/ Autobot Skids)
(looks like a doubling up of Skids if you want Mudflap AND the Track set)
(hope that is useful as a checklist for others)
