Sadly, there was no GatchaCon t-shirt for this year was because the person responsible for the shirt design and printing suffered some recent injuries. Hopefully he will recover soon!
There were some interesting promotions at the Imagi booth: fans could dress up as Ken and get their pictures taken in front of a Gatchaman-style background. There were also some Gatchaman freebies. There will probably be more at the 2010 Comic Con. Save your money for next year, because from what I've heard, the con (admission and lodging) is getting more and more expensive.
Check out the nice Gatchaman G-2 poster as well as the posters of the rest of the team here on Felix Ip's blog. (Thanks, Reboekah!)
