In the game's files they have all the different cinematics written out almost like a script.
Detailed information about the files for anyone who cares
For instance, you'll see stuff like this (Goku vs Jeice and Burter in TMQ 6)
cut1_1 Fram In GES & BAT & GKU (GES = Jeice, BAT = Burter, GKU = Goku)
cut2_1 GKU & BAT Side
cut3_1 GKU & BAT Fight Start
cut4_1 GES
cut5_1 GKU V.S BAT & GES Fighting
cut6_1 GKU Kick
cut7_1 GKU Kick Hit
cut8_1 GKU That Run After BAT
cut8_1 GKU Elbow Attack
cut8_1 BAT Fall Down
cut8_2 BAT Fall Down
cut8_1 GKU Catch
...
All of the above are comments added in by the programmers so that they'll be able to tell more clearly what each line means. Not included above is the actual code that executes or frames these events which look usually something like:
LuaGlue_AddCNCameraSplineSelf(0.0, 0.0, 0.0, 0.0, 0.0, 0.0, "TMQ6_S9_CAM_05", 0.0)
All of the cinematics in the game are in here, but there's then three more of them listed after TMQ 6. One has been there for a while, but went unnoticed (so I'm not sure exactly when it was added), and the other two were just added in the test server.
The first is called "TLB Proto Type"
Note: "TL" could be referring to "Time Leap" which are all of the single player time travel quests from the early levels. All of the Time Leap quests reward you with a skill that every class gets (power up, guard, block, and dash). If there's another Time Leap quest then it should also follow that there will be another skill (flight maybe?).
The script for these cinematics aren't nearly as commented as in my example above, but what I can make out is that it involves Vegeta, Nappa, and Radditz. The only other thing I can make out is that they all take their ape forms during the cinematic.
The last Time Leap quest we were given took place at the end of Dragon Ball (the anime) and this one would have to be before the beginning of DBZ. So it's entirely possible that this will become the next Time Leap quest. Also, seeing as they can all fly, it's also possible that we'll learn flight there.
The new cinematics added with the test server are called "DWC_001" and "DWC_002"
Again, the commenting is not very detailed; so I can only make how who will be involved. These two cinematics are also very short (only 1 scene long).
DWC1: Child Goku and "Pllnarodon" (might be a dinosaur)
DWC2: "Kame-Roshi" and Kame
