The new format is being issued for all approaches - I just pulled up the NDB A True at CYBK as an example. The beacon is on the field, so there's no timing, however they still give you suggested descent rates (and altitudes for certain GPS distances) for the CDA. There is only one PT altitude, not the "minimum" one plus a higher "CDA" one like other approaches, though this is due to the absence of a FAF as opposed to it being a circling only approach.
Do you have access to that plate? (*Edited to add: it's now posted at the same link I pm'd you earlier.)
I'll try to find another that's circling minimums only, but with a FAF.
