The British Christmas release is to not only include six episodes from the 15th and 16th Seasons, but will add a bonus disc for increased value.
The move, first revealed by amazon.co.uk, suggests a response to fan demands after concerns about the UK DVDs' values were raised following the four episode limit first introduced in 2010's Splish, Splash, Splosh.
The Christmas Tree Express, Ho Ho Snowman!, Salty's Surprise, Emily's Winter Party Special, Percy the Snowman and Tree Trouble are confirmed for the Christmas disc alongside extras Down at the Station and Guess Who?.
Merry Christmas Thomas!/Big Bang Surprise hits UK DVD shelves on October 28th.
Thanks to Hawk01 for the alert.
