A tale that may just come back to haunt Spidey in the coming months

[Mister Mets]

The solicitation for Swing Shift mentions that it's "a tale that may just come back to haunt Spidey in the coming months."

So can Dan Slott elaborate on that?
Could this lead to more Spider-man work for Slott? (and any elaboration would be appreciated.)
Or will another writer follow up on any developments?
Or does the "may" imply that the tale may not come back to haunt Spidey in coming months?

I was wondering if that birthday the solicitation mentions could be MJ's posthumous birthday (what with all the predictions of her death).
