AFAIK there aren't currently any changes planned for
ZiB
on ORF 2. It's worth noting that the changes to ORF eins are the result of ORF management's wish to significantly beef up that channel's news and current affairs output. As part of the changes, there will be an extra edition of
ZiB
every weeknight at 6pm, followed by the news magazine I mentioned at the top of this page; there will also be a current affairs talk show launching in May. I understand that ORF eins itself is also set to go under a rebrand, possibly going back to being called ORF 1.
