Not to be really dramatic or anything, but I'm very disappointed as I'll be attending D*C for the first time this year. It had been so exciting to think about! Thank goodness the f'list warned me not to get too excited.
This will be my 6th(?) Dragon Con, he's been scheduled to appear four times and appeared at one. Hence, me not getting overly excited when his name is mentioned. However, I understand what you are feeling. I've was there myself when he cancelled the first time.
