Would like to see more of Miles relationship with his mother since the first one was focused on the father-son relationship. The mother becomes concerned about Miles' unexplained absences and HER interfering mother starts to intervene. The mother is almost killed like she was in ulti-verse...
There'll probably be more on The Miles/Gwen relationship and maybe other teen girls . Anya Cortez? Was the purple haired girl at Miles' old school a young Jessica Jones?
But definitely more spideys : 2099, 1967, India, beastial mutant spidey, Superior (good plot twist). Maybe a HUGE ending where all the spideys appear (Electric company, 1980 Japan, 1990's cartoon, etc etc)
Singing dancing broadway spidey vs Bollywood Indian spidey during end credits...
