Joe Quesada has sunk Marvel with "events". Yeah the titles sell, but the writing really is half-assed now. Only a few Marvel titles (like X-Men, Hulk, Captain America, and She-Hulk) are still worth a damn as far storylines go, and that's only because Editorial DOES'NT interfere with what there doing (Cap's death is a mandate, but in this instance it's actually got a good story)
I've heard this is rumoured to be a big swerve that is meant to tie into Issue 600 of Amazing Spider-Man which will restore the marraige. Problem is, nobody has CARED about ASM or the mainstream Spidey for years and every cheap stunt Marvel makes to get back their readers (like "Sins Past" and "The Other") have only pushed more away.
I dtiched ASM a long time ago, and have been enjoying Ultimate Spider-Man and Amazing Spider-Girl (an alternate reality with Peter's daughter, but what really defines canon anymore? Especially since The Scarlet Witch warped reality twice)
