According to an article that I found from cbr.com : https://www.cbr.com/archie-comics-animated-live-action-series/
It seems that Archie comics will greenlight three shows,Two live actions and one animated series.So I thought of giving my guess on what the three shows are all about
The first live action show will be based on Josie and the pussycats and will likely set in the riverdale and chilling adventures of Sabrina universe with horror undertones,My guess is that it will be similar to the josie animated series from 1970 where the gang are caught in adventure/mystery situation but it will have a tone similar to the CW supernatural series where it will involve real supernatural forces and real criminal activities much like the X files.
Or maybe the josie live action series will have them turn into werecats or vampires like the one from afterlife with Archie
The second live action show will be based on an obscure character published by Archie comics from the 50s called Sam Hill, Private Eye which will probably be a crime drama television series but will likely be set in its own universe in other words a standalone series not connecting to the riverdale universe.
And the third will be an animated series but unlike the dark live action shows it will be light-hearted and family oriented and will be faithful to the source material that is comedy as it involves the misadventures of Archie and his gang though I wish that a live action sitcom or a comedy drama would be nice.
an thats all my guess on what Archie comic plan to greenlit three shows
