We’ll most likely always have generic minor league parks, unless SDS becomes convinced it’s worth the investment to get the rights to put the real minor league or spring training stadiums in the game.
Even if it were official already that the Blue Jays are going to start out in Buffalo/Dunedin, I’d still be surprised if SDS wanted to pay for the rights to get it in the game. It’s a temporary home that they might not even spend the whole season in. It’ll probably be like a normal season in The Show, with the Jays at Rogers Centre and full sized crowds in every stadium.
