Nerds, unite! Stars of some of the most beloved series in history are about to descend on the Treasure Valley!

Earlier this week, we shared the news that venue management at the Nampa Civic Center has chosen to call off this year's Treasure Valley Comic Con to avoid competing with the nationally branded Wizard World Comic Con.  Wizard World is scheduled to come to Boise just a week after the proposed date for the locally operated event. The convention sets up shop at the Boise Center July 13-15.

Tickets for one day, general admission range from $39.95-$44.95 or $79.95 for three day admission. VIP packages are quite a bit more spendy, but include some photo ops, autographs and themed merch from the celebs.  They're on sale already HERE! 

When we shared the news on Monday, Wizard World had not announced any guest information for their Boise installment of the show but that all changed a few hours later.  Take a look at who's been announced so far!

Editorial note: With so many Firefly stars on the card, I'm still keeping my fingers crossed for Nathan Fillion...because I've seen every episode of Castle at least six times.
