I did indeed notice that; and I loved that they did, makes me wish that IDW and Marvel would collaborate on an Official Handbook of the Marvel
TF Universe, featuring all the characters human and otherwise that appeared from Issue #1-80 and the
G2 series as well, they could even include a seperate title just for GIJoe and Cobra.
And I say why the hell not; it'd be nice to get an updated Universe style title for the old Marvel run, sure there's no new material to add for the most part, but it would offer more detailed information on the cast of human characters like G.B Blackrock, Josie Beller, Thunderpunch, Dynamo, Rapture and the like... Hell they could even do a Peter Parker/Spider-Man blurb detailing his history on that Earth and why he not only was the only mainstream Marvel hero involved on the TFs Earth, but also why he never reappeared after meeting Gears in Issue #3.
If they can ressurect history for characters like Deaths Head 1 & 2, Demolition Man, Copperhead, Diamondhead and all those other characters that never seem to get featured in Team specific books or the like, then they could certainly do the same for reality... Whatever you said it was, because I can't remember... After all I don't know about anybody else, but The All New Official Handbook to the Marvel Transformers/GIJoe Universe would probably sell just as well as all the other Official Handbooks, us comic geeks simply go gaga over profile/information/whatever you want to call it books.
