Quoted from frolic:Well, look at IMVE and you have your answer:
Tron VE:
-Based on "Pro"
-LEDs instead of incandescents (not color changing)
-Metal backbox
-possibly different toys because the originals aren't available
-Software updates slightly to work LEDs better
-Different translite art
I agree....minor differences to distinguish a "Vault" addition. Stern has my vote....I want one!
