I'm not all that interested in this product per se, but I'm considering buying it to encourage them to rerelease more retro products.
Personally I'd like to see new printings of the 2e AD&D campaign settings. Maybe even system neutral adaptations of them.
...
Actually, most of what I want at this point are reprinted modules and campaign stuff. Ideally with new art though...
Hell, if they dont want to commit to doing a print run, do color PoD copies on dtrpg. It's apparently working out well for WhiteWolf.
I wouldn't mind if they cannibalized the art from 3e and 4e, so long as the art is art of the same thing. Use the 3e Monsters of Faerun Helmed Horror image instead of a 2e one. Use 3e and 4e drow images in the drow modules. etc.
