Your fears are well-founded! We don't know what 2025 will bring with respect to the Creed - the emphasis appears to be more on the issue of the date of Pascha.
With respect to the Filioque, perhaps a formula could be agreed upon to make both sides happy.
IF the West would go back to the original Creed sans Filioque (Anglicans and others do use both versions with and without the Filioque), perhaps the Orthodox East could affirm that both "Through the Son" and "From the Son" are equally valid statements on the Spiration of the Third Person of the Most Holy Trinity. The issue with the Filioque in the East appears to be much more a canonical than a theological one - that the Creed of the earliest Ecumenical Councils was meant to affirm the universal faith of the entire Church, East and West (where the Filioque is an expression of specifically Western Triadology or Trinitarian theology).
So for example, the Orthodox Saint Mark Eugenikos, Archbishop of Ephesus known for his opposition to East-West Union principles established at the Council of Florence, originally came to attend the Council proceedings in the hope that reunion between East and West could be established once more (according to Fr Prof. John Meyendorff in a number of places in his published works). However, the sine qua non for the realization of such unity would, from the Orthodox perspective, be the original Creed without the Filioque. All else, namely theological differences as they developed since the break between East and West (whenever one believes that occurred . . .) were either open to negotiation or could remain as theological opinion or theologoumena that would not affect the unity of the entire Church, East and West.
Should the issue of the affirmation of the original Creed come to the fore during the 1700th anniversary of the First Ecumenical Council, I personally don't believe a return to the universal Tradition of the first Millennium, if properly explained and handled, would be an insurmountable problem for the West.
I don't know how they will settle the matter of the common date for Easter, if indeed that will be proclaimed in two years' time. If the Pope accepts the Eastern Paschalion as it is now . . . he may have Father Deacon (and Doctor) AJK to deal with!
A blessed Fast!
