I haven't really followed the thread, however I am surprised that there would be the possibility of watching Coliseum events...if that comes to be a reality, that would be really impressive, particularly if just anyone can join in to watch. Not sure how the rating system would allow it (PEGI/ESRB) but would be great to be able to bet on people too!

For dungeons I can understand how people might not want to be watched, however would be nice to be able to actively invite only those you wanted to watch it, rather than it being free for all viewing.
