Andrew Hussie's news post from April:
No updates on SDCC since then, but there is still a few weeks to go.San Diego Comic Con - July 12th - 15th
cosplay is not only welcome, it is encouraged. Feel free to completely swamp this thing with Homestuck characters. Let's outnumber all the storm troopers, animes and Spider Men combined. We will show up on the news under the headline, "COMIC CON RUINED FOREVER: HOMESTUCK OFFICIALLY REPLACES STAR WARS." I give you my blessing to make this happen, and reserve the right to renounce all personal responsibility.
I'll have specific signing times for both events, but I don't know exactly when those times will be yet! I will let you know when I do.
Is anyone attending this year? Are there any plans for a meet-up?
