This is what the Joecon wensite says:
Once again the Canadian Joe Con is proud to have Hasbro Canada on hand to answer all your questions about the G.I. Joe brand! In the past Hasbro has brought new and upcoming items to showcase and have conducted a Q & A Presentation for those same toys. It's too early at this time to comment on what they'll be doing, or bringing to the 2011 Convention, but we're sure it will be great, as always!"
