I see that the Bishop has given his reasons for removal of the Memorial Acclamation discussed below.
Unlike the other acclamations (i.e. “Dying you destroyed our death, rising you restored our life….) “’Christ has died…’ is more an assertion of the Paschal Mystery, rather than a unique expression of the gathered assembly of its incorporation into the Paschal Mystery.”
Ah, the usual liturgy-as-group-therapy-encounter communitarian bafflegab. As they say, "right result for the wrong reason."
Now, to move the argument up from the comment box:
No, there is nothing theologically suspect with the formulation as a general rule--not at all. It's a valued reminder of first and last things. But, in addition to the other problems noted: location, location, location. After the Creed--fine. After the Consecration--uh, no. Moreover, the alternate version ("Dying you destroyed our death") preserves the truths while at the same time acknowledging the Reality on the altar. Even though that Reality is not the cause of his objection, Bp. Trautman is still performing a helpful service here, whether he knows it or not.
