The line for next year's Comic-Con International in San Diego starts forming today. Preregistration for the 2013 convention starts at 8 a.m. Pacific today for those who attended the con this past July.

If you bought a four-day attendee or one-day attendee badge in 2012, you should have received an email with registration details for 2013--this doesn't apply to press, pros and exhibitors (exhibitor information can be found here). Pricing for next year's convention is available in this handy chart from the CCI site:

As noted in the con's registration badge sale FAQ, you'll need your Member ID account. You can buy passes for three other people besides yourself, as long as they also attended the con in 2012.

Open online registration will occur sometime in early 2013 for the general public. The 2013 SDCC will run July 18-21, with preview night on July 17.

Update, 8:16 a.m. Pacific: Preregistration has opened, with reports coming on Twitter of registration going slowly but steadily. "We are opening the waiting room door slowly to ensure that the system is running efficiently," one hopeful customer tweeted. Some report being #14,000 in line, while others are reporting they've completed registration. So it seems to be working.

"This beats waiting in line at 3AM...Maybe... depending on if I get tickets or not," Alienkid tweeted. Online preregistration replaces the usual at-the-show preregistration CCI has done in the past, meaning you spent part of your con waiting in line for tickets for next year's con.

Update, 8:26 a.m. Pacific: What the heck, here are some fun tweets as people wait in the virtual line:

lisi28: "Right now the #SDCC #Olympics are happening & everyone is fighting for a spot on the floor... Fight to the death #mortalkombat"

Tony B Kim: "If you listen quietly, you can hear the sound of nerds leveling up all across the interweb. #SDCC #tickets"

LibrariNerd: "Good thing this line isn't for Hall H, 'cause I'd never be getting in... #sdcc"

Comic Con Blog: "Typically people have multiple computer monitors to watch stocks. I have them for #sdcc tickets"

Update, 8:33 a.m. Pacific: According to folks on Twitter, the four-day + preview night tickets that were earmarked for preregistration are gone.

Update, 8:37 a.m. Pacific: Four-day passes are now gone--at least those that were earmarked for preregistration. If you missed them, don't fret--you'll have another chance during general registration. Which isn't saying much, I know ... they sell out pretty fast then, too.

Update, 8:58 a.m. Pacific: About an hour in, it looks like Friday-only and Saturday-only passes are gone as well.

Update, 9:19 a.m. Pacific: And preregistration is over.
