If we don't hold onto some hope the ban will be lifted and the DL declare his previous statements as wrong this is going to stain the Gelug tradition permanently decades or centuries into the future because people will reference his ideas as justifications. If he clarifies now, that will be taken as definitive and lots of arguing and division will be spared. Yes, there is still irreparable damage but better to fix something while there is time still and prevent future difficulties. If he does clarify that still doesn't mean the ban in the first place was justified, but rather I'd be willing to let some things go just to spare future difficulties.
If there is no hope for this then there is no point talking further at all....
i believe there is hope because it has been predicted. So it will definitely come to pass - it is just a matter of when. Many highly attained beings have indicated that the time is coming very soon so i think we will see history unfolding before our very eyes.
Perhaps it is the upcoming Dehli court case which will make the Dalai Lama rescind the ban... who knows. I just feel it in my bones that Dorje Shugden's snowlion is pawing the ground impatiently, huffing and puffing and waiting to dance across the skies!
I think one of 3 things could happen:
1) DL says definitively that the ban is lifted (whew)
2) one day, it just becomes okay again without DL expressly saying anything - this seems to happen within the Tibetan world. For example, it was a TERRIBLE thing for tibetans to go to Taiwan, and high lamas got into big shit for travelling to Taiwan... the one day DL himself makes a little trip there and now it's totally a-okay and nobody says anything anymore
3) nobody says anything, but soon, the anti-ds people just won't be heard anymore. This may happen when the Dalai lama passes away, for example. In the meantime, many DS groups, monasteries and teachers are gaining more and more influence in the world - not in a worldly sense, but in respect, even both the monastic and lay communities; in the number of Dharma centres or monasteries they have in the world; in their ability to teach the Dharma. In this increasingly educated world where people are encouraged and WANT to think for themselves, they are more likely to want to follow these lamas instead of the outdated TGIE who keep faffing about!
In a way, this is happening already. Many DS practitioners are not letting this issue sway their faith or practice and in fact have become stronger and more determined to uphold and preserve the lineage. They are becoming great beacons of faith to other DS practitioners... and so the good will and good energy spreads. people recognise truth and goodness when they see it, which they will most definitely see in DS practitioners and their wonderful, beautiful, truthful, kind lamas. That will be the greatest thing to quash the ban.
