The Dalai Lama's political power may be on the wane because he so wills it.By transferring political power to the new democratically-elected Prime Minister Sangay, he is showing clearly that he just wants to focus on spiritual matters and the Dharma in his remaining years.
Thus he is fully in control on the spiritual level. This is good because, even with the Dalai Lama-Dorje Shugden controversy, Tibetan Buddhism is spreading rapidly everywhere. He has made Buddhism a household word. As an emanation of compassionate Chenrezig he continues to teach and spread Dharma everywhere for the benefit of all.
Regarding his ban on Dorje Shugden practice, even when he spoke up about it recently, during a Kalachakra initiation in Washington DC(on the occasion of his birthday), it was like he was just doing so because the TGIE expected him to do so. I believe, he will continue to make a little noise here and there regarding his stance on Dorje Shugden practice. But that will be all.
The more interesting person to watch is the new Prime Minister. Will he be forced to make a statement about his stance on Dorje Shugden practice by the TGIE? Or will everything be kept as it is until the Dalai Lama is no more? Or will the Dalai Lama make an about turn concerning Shugden just before he passes on?
Whatever may be the case, Dorje Shugden's practice must continue to be supported and spread by not only the great Masters and high Lamas who practice Him, but by all who have found His practice so beneficial. This is so that the Dharma teachings of the great Je Tsongkapa and the Gelug lineage will continue to flourish for all times for the benefit of all.
