Many people that are new buyers won't admit it, but I would venture most, over 50% of these will end up hitting the for sale market within 1 year of getting it. Of the 4 people I know getting one, I can see all 4 doing it. 3 have sold one in the past as it wasn't their favorite game, and another thought it was a great deal and never had one on his want list.
So here is how I see it playing out:
1. Many of them have already owned and sold one in the past. So why not grab one, market has shown appreciation in this pin, sell and buy one of the many new pins coming out with a little extra in my pocket. They will dump them.
2. People that have bashed MM in the past are now owners. I guess buying one is going to make them a convert. They will dump
3. Flippers that flip all pins will buy multiples- gauge the market and sell when they can profit. Not if, but when, they will dump
The other 50%:
These are the people who really wanted a MM, they will keep the pin and be the new crop of forum defenders against the flippers who will proclaim, "I had the PPS MM and the game is over-hyped. I sold it within 2 months, as it did not do anything for me. I couldn't wait to dump it!!!!"
