Capcom could learn a thing or two from the 3DS Ambassador Program

With the 3DS Ambassador program under way for 3DS owners (hopefully, I don't have one so I don't know for sure), I got to thinking about the idea of an entity like Nintendo going out of its way to appease people for doing something like that. And eventually I got to thinking about Capcom, and Ultimate Marvel vs. Capcom 3. 
 
In case you somehow don't know, Capcom announced a while back that later this year they're putting out the aforementioned UMvC3, which features new characters, levels, gameplay tweaks, etc. And all the the bargain price of $40! What a deal! Unless of course you bought the original game in March at $60, thinking that Capcom had finally learned that people hate it when they do this. But no. They did the same thing they always do.  
 
But why couldn't Capcom do something like the 3DS Ambassador program? Do something to make people who bought the game at full price near its release feel like Capcom cares about us. It could be something as simple as mailing them a copy of the receipt and getting a discount on UMvC3. I know it'd go a long way to make me feel better about Capcom as a company.  
 
But of course they aren't going to do it because they know plenty of people are just going to buy the game regardless of what they charge for it, or what they try to do to appease people. And I will admit that my idea of mailing them receipts would be time consuming and costly on their end. But unless they have data on when each user took the game online for the first time, I am unsure of how they could go about it.  
  
Anyone else think this is a good idea? Or know of a more efficient way this could be accomplished? Or am I just dumb for not realizing this would happen, and wanting to buy the game within the week of its release to show support for it?
