Stardew Valley cross-platform multiplayer unlikely, says support team

We know that Stardew Valley on Switch is going to have multiplayer. After PC, Switch will be the first console to get it. Now would it be possible for Switch and PC players to play online together? According to the Stardew Valley support team, they aren't sure yet at this point, but it's "unlikely". Looks like you'll only be playing with other Switch players.
