If we look at the first JP movie, the following dino's had a main part:
- T-rex (already included in lots of JW1 en Junior sets, but still epic)
- Raptor (already included in lots of JW1 and JW2 sets, so I hope they won't include those)
- Dilo (already included in one JW1 set)
- Triceratops (NOT included, but they have the mold)
- Brachio (NOT included, but they have a mold from one of the previous lines, don't they?)
My bet is that they will include 2 larger dino's, probably one herbivore (guessing Triceratops) and one carnivore (T-rex, because it's just so important for that first movie).
Depending on price, they could:
- go ALL the way and give us a nice visitor center with a Jeep and a Ford
- give us just one vehicule (Jeep or Ford) and the gates (IMHO, that Junior set looks ok, but won't be a reason for TLC to NOT make a system set
- give us one of compound set (T-rex, Raptor) with one or 2 vehicles
I guess they would include all the minifigs in every set.
Just my 2c.
