I should be able to give you a better idea after the next ScotlandsPeople User Group meeting this coming Monday.
My present understanding is that the indexing and the imaging is complete, - in fact the database is up and running on the internal system at New Register House, i.e. not for visiting researchers,- but that there is a problem linking these RCE images to their register entries when there is a long period between the date of the original register entry and the date of the RCE. This can be decades, - I've seen 60 (sixty) years. The problem can then be that there has been a change in the registration district number in that period, - in fact in city areas there could be several changes. Unfortunately, not so easy to solve as it might first seem.
Let's see what the info is next Monday!
In the meantime your options are to order the £10 extract, or get someone visiting NRH to look at it for you. The RCE info will be on the back of the extract, or incorporated in the extract.
Although this probably doesn't apply in your case, note that the latter situation means that in the case, for example, of a birth originally registered as illegitimate and after that annotated with an RCE link following a successful paternity action, that RCE info on the father will be incorporated into the extract, and there won't necessarily be the info that this was via an RCE.
A clue to the possibility that there is a situation like this is if the extract is typed as opposed to being based on a photocopy of the register entry, but a typed extract is also supplied when the quality of the photocopy and/or the handwriting is judged to be inadequate
In general death register RCEs don't include anything more than the procurator fiscal's confirmation or his medical advisor's confirmation of the time, place, and cause of death, most often already on the death register entry, but, until you look, you never know
