After the recent update , you wondered when the new update would be added. The answer to this question is not certain, but the probability of being true is very high. The new update is likely to be in January.
Why?[]
As you know, the new update added a little christmas feeling. A new update comes up to remove them, and there is a possibility of new things coming up. But without the addition of something like V1.4.0.1 update may come, this is probably the most likely to be called 1.6.1.
