Not sure if this is old news or not, but having just found this myself I consider it fairly new (although I am generally about two months behind the rest of the world, so please forgive and humor me?)
So apparently this writer/producer named Lisa Joy has some relation to Sony and has made some waves (in a good way) noting that she really wants Gwen Stacy: Spider Woman in a movie and has decided the best way to do that is through having Silver Sable reality hop.
I'm not as jazzed about the Gwen Stacy deal as I am Silver Sable's return. I loved Silver and have her entire series, but as I do not follow Spider-Man as a rule, I missed out on her appearances there including her apparent death. I really wish Marvel would bring her back and give her a bit of a spotlight. She was somewhat unique at the time and could fill an interesting niche at Marvel currently.
