Holiday Prime packs were not added.

   From this week of December of 2017 compared to 2016 there was no additional Prime items added for the Holiday. In 2016 the month of December was given as a opportunity for the Prime Vault section to be added to the Market in game. There players were able to purchase Frost Prime and Ember Prime accessories, the Warframes with their full access as a bundle, and the mega bundle of both Frost and Ember Prime access. Last year that was great. As a possibiliy there can be the return of these packs on the following week starting December the 25. If it is not a sure thing to compliment, then the Prime Vault can be adjusted for. The Twitch Prime pack would have to be considered as a option to alter the return of the Prime Vault should the opportunity come as a plan B. In addition, there are other ways to implement the return of these Primes.

   Should plan A (The temporary return of the 2016 December Prime Vault), nor plan B (An adjusted Denver Prime Vault adjusted for, due to Frost Prime being in Twitch Prime) not work, then there are more options. Another option for the return to work is the original Prime Accessories for Frost and Ember Prime to be a Special Category from the Void Trader to have the Prime Syandanas for sell. Next as a option is to change the Twitch Prime; so a new pack of Vaulted items with new participation awards to start the 2018 year. That would give an opportunity a extra opportunity for the 2016 Prime Vault items to be returned to the game. Should December the 25 be too early to bring back these Primes, then the Prime Vault can be pushed into the new year and make the next month be a chance to have the Frost and Ember Prime be used for the Prime Vault. These many opportunities as general feedback can bring the other party of the Demeber experience that the Warframe player community has enjoyed.

   In all, to return Frost Prime and Ember Prime through some method of the change of the in game market would bring more approval in this time of the year from the Warframe community. There is other plans on the calender going on, such as the Acolytes returned currently, thr Kohra warframe, and Excalibur Umbra to be added to the game; but this Prime Vault has a good impact. It would be help more players enjoy Frost and Ember Prime, the Prime Accessories, and another chance for players to get more content in the game and purchase from the game.
