They will not directly honor the preorder. But, I can state from experience, same thing happened to me last year with the Mini NES. I successfully secured it online, then had it canceled. I showed up at the store, on day one, there were over 100 people in line. I walked to the front of the line and asked to talk to a manager. I explained the situation to the manager, and they gave me my system. I was very polite, not irate. I had "receipt" of proof of purchase. I said a receipt should take priority over someone who just shows up. I also asked them to check their security cameras, because I had been sitting in the parking lot for 4 hours before anyone else showed up and got in line. The manager put the system aside, and I watched a good 20+ people buy theirs before I finally got confirmation that I could have it. Now, then...This is where it gets very interesting. I furthermore emailed Corporate, explaining how well the manager handled things. I said, if there ever IS an SNES Mini (without even knowing there WOULD actually be one), I wanted a guarantee that I could walk in on day one and be the first to get it. Surprisingly, after talking to the store manager, I am absolutely guaranteed one on day one. To be honest, if the Mini SNES is incapable of being hacked, I will not be keeping it. I will offer it, at cost to the two people who posted here, that their preorders had been canceled. But, if I am able to secure any additional systems on day one, I will also let you guys know. When the Mini NES first came out, I was at work. I spent literally every free minute, breaks, lunch, etc. from 11:59 pm and on trying to "buy" a system. Every single site crashed. I was finally able to get one around 4:21 AM, then another at 6:30 am. I also got in line at one store, and was 4th in line, so had no issue getting a system...even though they only had 6. But, no go on that pesky controller! Never ever found one of those! While waiting in line, others showed up and I helped as many as I could find them online, like I did. After getting my system, I went to the store I mentioned at the beginning of this post. I went through all of this trouble because my one friend really wanted a system, too. He was unable to go and wait like me, since he was predisposed for that moment in time. But, anyways, that crazy, hectic day, from 6 am til 11 am, I found 3 systems locally, 2 of which went to friends...And, I helped 11 others find theirs too. After that day, I kept being keen on finding more, and helped a good 68+ find them. Every person that got one for a true reason, rather than for resell purposes, made me content. Even my wife told me I should jump on the bandwagon and sell it. But, I absolutely refused to profit off of it. I cannot stand the practice, as it ruins gaming for all of us. Price gouging is also one reason that makes Emulation more attractive, in many instances. Yes, the real deal can be awesome. But, is it worth the price of a used car? Not everyone has such entitlement
The only advice I can say is, if you are not adamant enough and focused enough on day 1, you will probably never get a system. I literally told a half dozen friends on day one where they could get systems, and they didn't care. They said, "I will get one another time". I said, this is probably your "final" chance dude/dudette! Noone listened, and later on when I had an extra system...unfortunately, I gave priority to those who "were" looking for one since day one, rather than those who didn't take day one seriously enough to bother. Sorry for the long post! But, it comes with the territory of how much hell many of us went through trying to get a damned system!
