Umm, no, I have been following this since it was first reported, but have never experienced it until this morning. I've had my car since May. I just figured I got lucky.

Looks like you haven't been following the pinging problem threads much. Only some of the STi's have a serious pinging problem that merits a reflash. If that's the first time you've heard it, and it's mild, then mostly likely there's absolutely nothing wrong with your car. Those with the problem probably have a too aggressive knock/learn programming. Your's is probably "just right", where it advances timing enough to detect a little knock.
The reflash may end up being exactly like what you have currently.
