HP at drupa, what to do with a B2 sheet? Will there be much inkjet publishing near Bristol?

HP have a video that features a B2 sheet and also inkjet for publishing.

I wonder what the use would be for a short run of B2 sheets. Other presses are available ( but not yet found on YouTube with recent uploads).

Inkjet devices for newspapers are very expensive. There might be one in Bristol for a regional publication. I still find the Guide in the Saturday Guardian very annoying in the doubled up pagination. I have to rip the localised bit out to make sense of the TV films. This is the sort of thing inkjet could improve. What else?
