MON/ZB are not re-considering a move to T2 from what I hear, whether they get airbridges or not is not an issue, and even now at T1 many of their services are remote or B-pier steps.
EZY are still moving to T1 as planned, and show no signs of dissatisfaction with MAN - indeed, quite the opposite.
Another terminal move to keep an eye on is KLM to T3 to join AF which is strongly rumoured to be in the pipeline.
