In the UA, it was:
• Acolyte - Magic Initiate (Divine, presumably now Cleric)
• Artisan - Crafter
• Charlatan - Skilled
• Criminal - Alert
• Cultist - Magic Initiate (Arcane) seemingly cut
• Entertainer - Musician
• Farmer - Tough seemingly cut
• Gladiator - Savage Attacker seemingly cut
• Guard - Alert
• Guide - Magic Initiate (Primal, presumably now Druid)
• Hermit - Magic Initiate (Primal, presumably now Druid)
• Laborer - Tough seemingly cut
• Noble - Skilled
• Pilgrim - Healer seemingly cut
• Sage - Magic Initiate (Arcane, presumably now Wizard)
• Sailor - Tavern Brawler
• Soldier - Savage Attacker
• Urchin (seemingly now Wayfarer) - Lucky
Both of the backgrounds that grant Tough were cut, but Criminal and Guard double up on Alert so I would guess one of them picks up Tough, probably Criminal. Pilgrim was cut and Hermit and Guide double up on Magic Initiate (Druid) so I would guess one of them picks up Healer. No idea what the new Merchant and Scribe would get.
