Well, personally I do understand your feelings, but just a short example from my experience:
I've bought my first copy of FSX on the day1 for $80 canadian +TAX.
Yesterday I got one more copy, just for $60. Probably in a few months I'd find it for $29 in bargain bin.

Also I got all MS FS boxes since FS98 (all of them purchased on the day1), but for some reason I never got a penny of discount.

But I'm absolutely fine, because it's not the way MS treats me (loyal early bird) but it's just standard software marketing.

Anyways, we are about to launch our new more powerfull online system, so hopefully we'll find a way to thank our loyal customers somehow.
