Iorveth - status in game (Spoilers)
A few days ago, i ran into a Random encounter near Oxenfurt.I helped a scoia'tael escape from some foes. Then,he asked me to meet him in a camp nearby,so i followed him. When i got there i saw two scoia'tael talking and one of them said:
"He was so full of arrows that looked like a porcupine.Believe me,Iorveth is dead.Deireadh."
If what he said is true,our main choices in TW2 won't change almost anything.
Here is the video showing what he said, but it is in portuguese:
