Spider-Man#11 and ASM#31 are said to be going into more details about his background but maybe with the new solo it maybe clarified there.
It seems that the trademark was cancelled due to failing to timely file the proper renewal paperwork and Marvel has recently file a new paperwork .
I would not underestimate the appeal of Spider-People, particularly one aimed at kids.
If Moongirl can make it to almost 50 issues I think Spider-Boy has a good chance of reaching close to that.
