Pan-F is not coated on the thick base used for LF so they won't cut it to sheets: it'd be really horrible to handle like the Rollei is. I expect Pan-F on 70mm is physically reasonable given their current coatings but I don't think they plan to offer that as an option.

I expect any Pan-F sales in 70mm would directly cannibalize FP4 sales, therefore offering it is a losing proposition for Ilford (more cuts, more wastage and no sales increase).

I have absolutely no use for 116.
