There is talk that WWE NXT star Leo Kruger debuted a new gimmick and name at a NXT live event last week. Apparently he is now called Adam Rose. However, Kruger worked last Thursday's NXT tapings and will be appearing on the December 18th and December 25th episodes under his normal name. Kruger's Twitter hasn't been changed either so either there's nothing to it or he could be debuting the new gimmick after the December 25th episode airs.
On a related note, more videos recently leaked from a NXT presentation class and embedded above is a promo Kruger cut on the WWE creative team.
Here is a photo of Kruger as Adam Rose:
