Here is a link to a recent interview given by Fr. Robert Taft SJ, the worlds most prominent expert on Byzantine Liturgy. He gives a very good idea of what unity of East and West would be.

Here is just one VERY important point.
CWR: Most Catholics probably envision future unity between the Orthodox Churches and the Catholic Church as a re-installment of one world Church organization with the pope of Rome at the top of the governing pyramid. A look at history shows that such a model never existed, so what could Orthodox-Catholic communion actually look like if it were achieved? A renewal of Eucharistic communion? The possibility of an eighth ecumenical council? A resolution for the dating of Pascha/Easter?
Taft: What it would look like is not a “reunion” with them “returning to Rome,” to which they never belonged anyway; nor us being incorporated by them, since we are all ancient apostolic “Sister Churches” with a valid episcopate and priesthood and the full panoply of sacraments needed to minister salvation to our respective faithful, as is proclaimed in the renewed Catholic ecclesiology since Vatican II and enshrined in numerous papal documents from Paul VI on, as well as in the wonderful Catechism of the Catholic Church. So we just need to restore our broken communion and the rest of the problems you mention can be addressed one by one and resolved by common accord.
