It will indeed be possible to backup sites/ documents lists and pages with version 2.0. Functionality will be more or less similar than what you can do today with a virtual SharePoint on-premises (look at our current functionality in Veeam Explorer for SharePoint to see what you can restore today).
We won't generate it in a VBK version however. Since the way backup works in VBO for Exchange Online is different than our traditional VBR product, backup of SharePoint (and storing the data) will be different also.
So restore of lists to a CSV file won't be possible today and that won't be in the next version either. PowerShell restores however will be possible.
For the release date. It is ready when it is ready
. On a serious note, I can't give you a release date at this moment (and we never do at Veeam) but Beta is getting closer. (So yes, there will be a beta program)
