[About the regular identity disk] Unfortunately, it does not glow in the dark. This was a bummer to myself and everyone else working on the toy line. But, it does fly quite well.
Also, the Deluxe Identity Disc is a bit smaller...it is the exact size of the props used in the Tron Legacy movie. The Identity Disc is larger for flight purposes.

Unfortunately, these things often come down to cost (No glow in the dark-Basic Disc) & safety issues (not a flying toy-Deluxe Disc). You'd be surprised how expensive it would have been to adhere to modern Glow-in-the-dark safety standards while also
a.) molding the entire disc in glow-in-the-dark plastic
or
b.) painting large portions with glow-in-the-dark paint.
In the end, a 'frisbee' isn't meant to be played with in the dark anyway, so everyone involved agreed that this was the best path to go down while still offering a flying Disc at a reasonable price point. I think both discs are good items, they just have very different purposes.
The good news is, what was shown at Comic Con isn't the end of line for Tron toys.
Sorry if any of that sounds like something a 'company-man' would say, just trying to give you some insight as to why certain decisions are made. We want awesome toys too
