Will 100% be remade/rebooted.
Most people don't know that there are actually 5 movies in the series, so Fox has tried their best already to milk the series.
EDIT:
Have a look at the synopsis/info for these 3 movies lol:
Home Alone 3 (1997)
Home Alone 3 does not center on Kevin, but instead on Alex Pruitt, a young 8-year old boy who gets infected with chickenpox but soon recovers. At the same time, four criminals working for a Hong Kong-based North Korean terrorist group are sent by their boss to retrieve a top-secret microchip that can act as a cloaking device for a missile. They succeed in retrieving it and hide it in a remote controlled car, but due to a luggage mix-up at the airport with the Pruitts' neighbor Mrs. Hess, the car lands in the hands of Alex who is given the car for shoveling the snow in her driveway. The criminals begin systematically searching every house on his street, which Alex stumbles upon while home alone. Once they realize he has the chip, they prepare to invade his house. He devises elaborate traps and bamboozles the four crooks with the help of his pet rat, his brother's pet parrot and some intricate tripwires, all the while monitoring them with a video camera on the race car. The film was nominated for a Golden Raspberry Award for Worst Remake or Sequel, eventually losing the award to Speed 2: Cruise Control. It is the last film in the series to be theatrically released.
Home Alone 4: Taking Back the House (2002)
The fourth installment was directed by Rod Daniel and premiered as a television film on ABC on November 3, 2002. This film returns to the original's main character, Kevin (played by Mike Weinberg), and one of the two Wet/Sticky Bandits, Marv (played by French Stewart). Kevin's parents have separated, and he lives with his mother. He decides to go spend Christmas with his father and his rich girlfriend, Natalie, but finds himself having to deal with his old nemesis Marv, and his new sidekick wife, Vera (played by Missi Pyle), who replaces Harry since he and Marv put their partnership to an end. It was released to Region 1 DVD on October 20, 2003. Filming began on July 29 in Melbourne. Home Alone 4: Taking Back the House is the first film in the series that was not theatrically released.
