This version of Lambor / Sideswipe lacked the painted Autobot symbol but instead comes with two different sized Autobot symbols much like MP-12T Tigertrack.
Like all Transformers Expo exclusives, this figure is going for quite a bit of money ($100+) on most Japanese sites. I acted quick and got mine for $70.
Obviously this release is a very minimal change and not even really that convenient (unless you were at TF Expo) to acquire. Though I do like the lack of a symbol for the clean car look.
