The op has a sweet collection, 100% positive reviews and is lucky to have this gorgeous game.
As Paul (sepins) and the op have already said, there is little profit to speak of. People busting balls are simply jealous and/or clueless.
Will this game be slightly less costly months from now? Maybe. So what?
I just paid a 1k premium to pickup a local/loaded Rick and Morty...best decision ever. Love the game and can enjoy it with my son who will be visiting. Will it be worth more/less 1 years from now? No clue.
