They've always leaned towards Friday morning drops for each bigger promotion that's happening for Madden 22 Ultimate Team, and they may start at any point next week or even earlier.
However, we'll most likely get the program teased on a Wednesday edition Good Morning Madden, get an official announcement with the majority of the players on the following Thursday's edition of Good Morning Madden, and it will conclude with the program drop during the Friday dawn. That could place the first drop as early as December 3, 2021, however they've usually waited more than a month to begin the month which is why it's likely to be around December 10, 2021.
One thing you can count on from Zero Chill and any possible December MUT Promotion that's been announced, is you'll get new cards with Madden 22 Ultimate Team. These programs usually come with other missions and challenges however they all revolve on a new set of cards that players are pushing to join their Ultimate Team.
Predicting which players will be selected is a challenge as it can vary widely, but Zero Chill has had a variety of past and present players within the group before. There's a good chance that we'll see some legendary players and some current day players at the very top of the lineup to ensure that things are balanced The rest of the lineup will change based upon the teams' current roster.
We could also see coming back Snow as a currency, companion promos like Ghosts of Madden and Snow Beasts or the addition of the present mechanics Zero Chill was able to use in MUT last year.
