We are very likely to get a series of fights based on new monsters added in WotG.
Well, first thing to note is that the three instanced areas seemed to double as battlefields. Additionally, there are hidden additions to the map that could be used as well.
Aside from the tiger and coeurl variants, there has been 6/7 additions:
Peiste
Gnat
Ladybug
Rafflesia
Slug
Pixies
(and Sandworm, though I doubt a normal orb-like battle with him)
We are very likely to get 6 battles split between the three nations' instanced areas.
