Okay, in all the combing through the internet, I found a few sources of information for stuff that was discussed at the Hasbro IDW panel, but unfortunately none of it ended up really being of any consequence.
The first intel came from YoJoe, who had a representative in the panel, and the recap can be found right here, though honestly not much was revealed.
Essentially most of the panel seemed to focus on Cobra and how they got in the position they’re in now, which is pretty fascinating to consider.  Cobra’s whole history back in the day was pretty odd, considering how much force and technology they amassed without it really being discussed just how they did it, where the money came from (beyond a “pyramid scheme”) or how they built their empire.  The IDW universe is playing into that a LOT more, and it’s pretty neat.
One of the more interesting notes was the fact that an upcoming issue of G.I. Joe, the first appearance of Storm Shadow proclaims itself as the end of “Season 1” of G.I. Joe.  I’m not entirely sure how they break up the “seasons” or if they simply mean the book is moving in another direction from that point on.
The most comprehensive coverage of the IDW panel was posted on The Terror Drome (with some props as well to iFanboy) and their run down is as follows:

• After 3-part Zartan story in Origins, Croc Master “origins” story in issue #18.
• Hama returns to Origins for one more story with G.I. Joe: Origins #19 which will be another “silent issue” featuring Snake Eyes.
• Then G.I. Joe: Origins 20-23 will focus on Cobra organization.
• G.I. Joe: Cobra Special #2, available last week of September, featuring the trial of Erika le Tene.
• Chuckles story concludes in G.I. Joe: Cobra #10-13
• In the main ongoing G.I. Joe title, critical mass device #23-27, Storm Shadow first appearance in IDW verse.
• G.I. Joe: RAH will pick up from Marvel’s run with Cobra presenting itself as a “Blackwater” type organization.
• Both G.I. Joe: Renegades and Transformers Prime will have books debuting in October”

So, in all honesty, not a whole lot of juicy new intel was released…but we’ll take what we can get.  Thanks to everyone for chipping in links and coverage so we could get this all together.  Big thanks to Wild Weasel of The Terror Drome as well, for finally getting some comprehensive details of the panel.
