Will the Yotaphone 2 ever receive Lollipop 5.1.1.?

there are significant bug fixes and performance enhancements in the latest version of Lollipop.

Will our phone see this upgrade which imo is highly required as it has been subpar since the move from Kitkat. I've noticed overheating and increased battery consumption in day to day use on lollipop.

With the American launch cancelled. Yota moving to sailfish and the poor sales, I feel doubtful.
