Upgrading is not enough to get the NM offer. You also have to be targeted for it. It's not clear, for example, if they're already done targeting everyone they're to target. (If that is indeed the case, then no one who gets the card now, whether through upgrading or "from scratch", might get targeted, even if they might have been targeted had they had the card already earlier this year.)

And not everyone who has the card got that particular NM bonus. That's been documented in recent pages of this thread.
