Let's see...

Colors: the red is more of an orange-ish shade and the blue is brighter. The gray on the trailer is lighter as well. These are possibly an attempt to better match cartoon colors.

Mold: short stacks and longer missiles (safety laws), reinstalled launching gimmick for Roller (removed for TRU reissue), blue Roller (TRU's was gray). There are other smaller differences, but mostly in the construction and not really noticable unless you're specifically looking for them.
