I work in a building full of older people, I just don't see a pin like this being of interest to them. The window for the generation that grew up with the Beatles and having that much disposable income.. has shrunk pretty hard in the last few years.
Guess we will find out when the pin is released how well the sales are. Personally I played Seawitch several months ago and it was fun, I'd rather see it re-released at some modest price point and buy that over the Beatles offering...
