Although it's anyone's guess as to what McDonald's will reveal in the "big announcement" it has planned for January 26th, there's at least one new menu change you safely rule out now: new Big Mac sizes. Why? Because they're already here.
After first introducing the new cheeseburger form factors in test markets last year, McDonald's has rolled out the new sandwiches -- the Grand Mac and the Mac Jr. -- to it's more than 14,000 restaurants nationwide, according to a report by the Chicago Tribune. As their names suggest, the new burgers are made with all the classic Big Mac ingredients -- all-beef patties, special sauce, lettuce, cheese, pickles, onions -- on a sesame seed bun -- in bigger and smaller packages.
