Steam page for Mortal Kombat 1 now states that 'Cross-Platform Multiplayer' is included as a main feature. Though we knew crossplay would be coming to MK1 at some point, there was still questions as to whether PC players would be included in that because the game is not being handled solely by NetherRealm Studios on the platform, but rather QLOC. If you were waiting for crossplay on PC before picking the game up, though, you might not want to jump to the pre-order button right this second since this hasn't been officially stated and confirmed by NRS or Warner Bros
