Not really. I think I only found two GI Joe Q&As from SDCC, The Terrordrome one you posted and one over at YoJoe.com. I'm not sure if some of the other Joe sites actually had dedicated personnel at SDCC to do their Q&As.
The most interesting part of that entire interview, however, is the fact that HTS will only do one show per year now, and that show will alwasy be SDCC. Anyone else think that's why they killed the Celebration VI exclusive, not because of some timing issue or whatever, but because the accountants decided that the store wouldn't travel?
And from all accounts, it sounds like Hasbro will have no presence whatsoever at NYCC anymore, not even a display booth and panels. They're just not going at all now by the sounds of it.
So, basically, you get Hasbro at Toy Fair and SDCC and MAYBE Celebration and MAYBE Joe and Bot Cons... But Celebrations aren't every year and who knows how much longer they'll decide to go to the two Fan Club events...I assume they'll want to be at those because it's their own licensed product but what about future Celebrations? I guess LFL could demand they be there as the #1 license holder, but it sounds like the best we can hope for now is some display cases and a presentation out of them.
