IMO, sure striking should have a bullet put into it.
It shouldn't be allowed to bypass alignment DRs, special material DRs, or epic enhancement bonus DRs.
It's possible that something called "sure striking" may appear in a future 3.5 product, but its effect isn't likely to bear much resemblance to the property found in MaF. (In this case, we'd be "revising" simply to indicate that the old effect no longer exists.) For instance, maybe a new "sure striking" property could work something like Blind-Fight (roll miss chance twice vs. concealment). That wouldn't be ideal, because I'd rather not have a cheap weapon property that duplicates a feat, but I might start with that concept were I to design a new "sure striking" property.
Of course, strictly speaking, sure striking can still exist exactly like it is. It'll have no game effect against a creature with 3.5-style DR, but that doesn't mean that it "doesn't work".
